Welcome to the wonderful world of elements! Do you ever find yourself wondering what element is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6? Or maybe you’re curious about 1s2 2s2 2p6 3s2 3p6 4s2 3d3? Or even 1s2 2s2 2p2 3s2 3p6 4s2 3d6?
Elements are the building blocks of the world, and understanding them can be incredibly rewarding. In this blog post, we’ll explain what elements are, what the different configurations mean and how to identify them. We’ll also provide information on the elements associated with 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6, 1s2 2s2 2p6 3s2 3p6 4s2 3d3, 1s2 2s2 2p2 3s2 3p6 4s2 3d6, 1s2 2s2 2p6 3s2 3p6 and 1s22s22p63s23p64s13d5.
Elements are the most basic form of matter, and they are composed of atoms. An atom is the smallest unit of matter that can exist, and it is composed of protons, neutrons and electrons. Protons and neutrons make up the nucleus, and electrons orbit the nucleus in shells. The electrons are arranged in a specific pattern, which is known as the electron configuration. The electron configuration provides information about the atom’s structure, and it can be used to identify the element.
Each element has a unique electron configuration, and the arrangement of electrons can be described using the shell model. In this model, electrons are arranged into shells, and each shell is divided into sub-shells. Each shell can hold a certain number of electrons, and each sub-shell can hold a certain number of electrons. The shells are identified by a number, and the sub-shells are identified by a letter. For example, the 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 configuration indicates that the element has two electrons in the first shell, two electrons in the second shell, six electrons in the third shell, two electrons in the fourth shell and six electrons in the fifth shell.

What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d3?
The electron configuration of an element is a representation of the arrangement of electrons around the nucleus of an atom. It is an important concept in chemistry, and can be used to identify an element and predict its properties, including its reactivity and its bond strengths. The most common form of electron configuration is the one-electron configuration, where all of the electrons of an element are arranged in shells around the nucleus. The 1s2 2s2 2p6 3s2 3p6 4s2 3d3 electron configuration is the configuration of the element palladium.
Palladium (symbol: Pd) is a silvery-white metal that is part of the transition metals group. It is a rare element that has many uses in industry, including in catalysts and electronics. It is also used in jewelry and coins, and is sometimes used as a substitute for platinum. Palladium is highly reactive and has a melting point of 1554.9 °C (1830.6 °F).
The 1s2 2s2 2p6 3s2 3p6 4s2 3d3 electron configuration can be broken down into the following parts:
1s2
This is the first shell of electrons around the nucleus. It is filled with two electrons, which are in the 1s orbital. This orbital is located at the closest distance to the nucleus, so the electrons in this shell are the most tightly bound to the nucleus and experience the most attraction.
2s2
The 2s shell is the second shell of electrons around the nucleus. It is filled with two electrons, which are in the 2s orbital. This orbital is located at a slightly larger distance from the nucleus, so the electrons in this shell experience less attraction from the nucleus than those in the 1s shell.
2p6
The 2p shell is the third shell of electrons around the nucleus. It is filled with six electrons, which are in the three 2p orbitals. These orbitals are located at a greater distance from the nucleus, so the electrons in this shell experience less attraction from the nucleus than those in the 1s and 2s shells.
3s2
The 3s shell is the fourth shell of electrons around the nucleus. It is filled with two electrons, which are in the 3s orbital. This orbital is located at a greater distance from the nucleus, so the electrons in this shell experience less attraction from the nucleus than those in the 1s, 2s, and 2p shells.
3p6
The 3p shell is the fifth shell of electrons around the nucleus. It is filled with six electrons, which are in the three 3p orbitals. These orbitals are located at a greater distance from the nucleus, so the electrons in this shell experience less attraction from the nucleus than those in the 1s, 2s, 2p, and 3s shells.
4s2
The 4s shell is the sixth shell of electrons around the nucleus. It is filled with two electrons, which are in the 4s orbital. This orbital is located at a greater distance from the nucleus, so the electrons in this shell experience less attraction from the nucleus than those in the 1s, 2s, 2p, 3s, and 3p shells.
3d3
The 3d shell is the seventh shell of electrons around the nucleus. It is filled with three electrons, which are in the three 3d orbitals. These orbitals are located at a greater distance from the nucleus, so the electrons in this shell experience less attraction from the nucleus than those in the 1s, 2s, 2p, 3s, 3p, and 4s shells.
The 1s2 2s2 2p6 3s2 3p6 4s2 3d3 electron configuration is the electron configuration of the element palladium. Palladium is a rare element that has many uses in industry, including in catalysts and electronics. It is also used in jewelry and coins, and is sometimes used as a substitute for platinum. Palladium is highly reactive and has a melting point of 1554.9 °C (1830.6 °F).
When looking at the electron configuration of an element, it is important to remember that each shell can only hold a certain number of electrons. For example, the 1s shell can only hold two electrons, the 2s shell can only hold two electrons, and so on. Each electron must occupy its own orbital, so the 1s shell cannot hold more than two electrons, the 2s shell cannot hold more than two electrons, and so on. This is why it is important to understand electron configurations, as they can help to identify elements and predict their properties.
What is the element of 1s 2s 2p 3s 3p?
Atoms are composed of electrons, protons and neutrons. Electrons are arranged around the nucleus in shells or orbitals. The electron configuration of an atom is a representation of the arrangement of its electrons in various orbitals. The element of 1s 2s 2p 3s 3p is the electron configuration of an atom with five electrons.
The electron configuration of an atom is determined by the energy levels and sublevels of the electron orbitals. The energy levels are determined by the principal quantum number (n) and the sublevels are determined by the azimuthal quantum number (l). In the case of 1s 2s 2p 3s 3p, the principal quantum number is 1 for the 1s orbital, 2 for the 2s and 2p orbitals, and 3 for the 3s and 3p orbitals. The azimuthal quantum number is 0 for the s orbitals and 1 for the p orbitals.
Order of Filling Subshells
The order of filling subshells determines the electron configuration of an atom. The 1s orbital is the first to fill, followed by the 2s and then the 2p orbitals. The 3s and 3p orbitals are next, followed by the 4s and 3d orbitals. The order of filling is then 4p, 5s, 4d, 5p, 6s and so on.
Maximum Number of Electrons in a Subshell
The maximum number of electrons that can be accommodated by a subshell is given by the formula 2*(2l + 1). Therefore, the s, p, d, and f subshells can accommodate a maximum of 2, 6, 10, and 14 electrons, respectively. All the possible subshells for values of n up to 4 are tabulated below.
Principle Quantum Number Value | Value of Azimuthal Quantum Number | Resulting Subshell in the Electron Configuration
n=1 l=0 | 1s
n=2 l=0 | 2s
l=1 | 2p
n=3 l=0 | 3s
l=1 | 3p
l=2 | 3d
n=4 l=0 | 4s
l=1 | 4p
l=2 | 4d
l=3 | 4f
It can be understood that the 1p, 2d, and 3f orbitals do not exist because the value of the azimuthal quantum number is always less than that of the principal quantum number.
Notation
The electron configuration of an atom is written with the help of subshell labels. These labels contain the shell number (given by the principal quantum number), the subshell name (given by the azimuthal quantum number) and the total number of electrons in the subshell in superscript. For example, if two electrons are filled in the ‘s’ subshell of the first shell, the resulting notation is ‘1s2’.
Example
The 4p subshell is filled next by six electrons (Ga through Kr). As you can see, the periodic table shown in Figure (PageIndex{3}) provides a simple way to remember the order of filling the subshells in determining the electron configuration. The order of filling subshells is the same: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, etc.
Example (PageIndex{2}): Aluminum
Using Figure (PageIndex{3}) as your guide, write the electron configuration of neutral aluminum atom. The atomic number of Al is 13.
Solution: Aluminum has 13 electrons. Start at Period 1 of the periodic table, Figure (PageIndex{3}). Place two electrons in the 1s subshell (1s2). Proceed to Period 2 (left to right direction). Place the next two electrons in the 2s subshell (2s2) and the next six electrons in the 2p subshell (2p6). Proceed to Period 3 (left to right direction). Place the next two electrons in the 3s subshell (3s2) and the last one electron in the 3p subshell (3p1). The electron configuration of Aluminum is 1s22s22p63s23p1
Using Figure (PageIndex{3}) as your guide, write the electron configuration of the atom that has 20 electrons
Answer: Start at Period 1 of Figure (PageIndex{3}). We can also use the block organization of the periodic table, as shown below, to remind us of the order in which sublevels are filled. To do this, we move through the elements in the order of increasing atomic number, listing new sublevels as we come to them. The type of sublevel (s, p, d, or f ) is determined from the block in which the atomic number is found. The number for the principal energy level (for example, the 3 in 3p) is determined from the row in which the element is found and the knowledge that the s sublevels start on the first principal energy level, the p sublevels start on the second principal energy level, the d sublevels start on the third principal energy level, and the f sublevels start on the fourth principal energy level.
We know that the first two electrons added to an atom go to the 1s sublevel. Atomic numbers 3 and 4 are in the second row of the s block (look for them in the bottom half of in image below), signifying that the 3rd and 4th electrons are in the 2s sublevel. The next six electrons go to the 2p sublevel (2p6), followed by the 3s and 3p orbitals (3s2 and 3p6). The last two electrons go to the 4s subshell (4s2). The electron configuration of the atom with 20 electrons is 1s22s22p63s23p64s2.
Understanding the element of 1s 2s 2p 3s 3p is important for understanding the electron configuration of atoms. Knowing the order of filling the subshells and the maximum number of electrons in a subshell can help you to write the electron configuration of an atom quickly and accurately.

The Aufbau Principle
The Aufbau principle dictates that electrons will occupy the orbitals having lower energies before occupying higher energy orbitals. This principle is named after the German word ‘Aufbeen’ which means ‘build up’. The energy of an orbital is calculated by the sum of the principal and the azimuthal quantum numbers. According to this principle, electrons are filled in the following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.
Box Diagrams of Electron Configuration
If an atom has a partially filled sublevel, it may be important to know how the electrons of that sublevel are distributed among the orbitals. Research has shown that unpaired electrons (a single electron in an orbital) are in a lower energy configuration than are paired electrons (two electrons in an orbital). The energy of the electrons in a sublevel would then be lower with half-filled orbitals than with some filled and some empty. We can show the distribution of electrons by using box diagrams, where each box represents an orbital and the arrows within the boxes represent the electrons in that orbital.
Pauli Exclusion Principle
The Pauli exclusion principle states that a maximum of two electrons, each having opposite spins, can fit in an orbital. This means that the supercripts (2, 2, 6, 2 and 2) in the electron configuration of Silicon add up to 14, which is the atomic number of Silicon.
Filling of Atomic Orbitals
The period or row numbers 1 through 7 are the energy levels of the elements. The s orbital holds a maximum of 2 electrons. The p orbital can hold 6. The d orbital can hold 10. The f orbital can hold 14 electrons. But, the orbitals overlap. The Madelung rule gives the order: 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s < 5f < 6d < 7p. Oganesson (element 118) is a good example to show the order of the orbitals. Its electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6. Alternatively, write the symbol for the noble gas before an element (radon, in this case), and just add the extra information: [Rn] 5f14 6d10 7s2 7p6. It is important to note that there exist many exceptions to the Aufbau principle such as chromium and copper. These exceptions can sometimes be explained by the stability provided by half-filled or completely filled subshells. Additionally, the real electron configuration of an atom may differ from the prediction because of relativistic effects, shielding, etc. In conclusion, the element with the electron configuration 1s22s22p63s23p64s13d5 is Silicon, which has an atomic number of 14. This can be determined by following the orbital-filling chart in Figure 5.9 and the electron configurations of the first 18 elements in Table 5.2 as well as by understanding the Aufbau principle and the Pauli exclusion principle. Additionally, the Madelung rule gives the order of the orbitals and understanding the exceptions to the Aufbau principle may be important in some cases.
