Do you ever get confused about electron configuration? If so, you are not alone. Electron configuration is a complex topic that can be difficult to understand. It involves understanding the structure of atoms and how electrons are arranged around them. Knowing the electron configuration of an atom is important in chemistry, physics, and biology. It is also necessary in order to determine the properties of a particular element.
In this blog post, we will discuss what the electron configuration 1s2 2s2 2p6 3s1 means and how to figure out the electron configuration of different elements. We will also go over some examples of electron configurations and how to identify the element associated with a given electron configuration. Finally, we will provide a simple guide to help you understand electron configuration in no time.
Electron configuration is the arrangement of electrons in an atom’s orbital shells. To determine the electron configuration of an atom, you need to know its atomic number. This is the number of protons in the nucleus of an atom and is also equal to the number of electrons that it has. The atomic number of an atom determines its place on the periodic table.
For example, the electron configuration of sodium (Na) is 1s2 2s2 2p6 3s1. This means that the atom of sodium has 11 electrons, with two in the first shell, two in the second shell, six in the third shell, and one in the fourth shell. The super subscripts (2, 2, 6, 1) are the number of electrons in each orbital. Simply add up these numbers, which will give you 11. Now just look for the element on the periodic table with the atomic number of 11.
Similarly, the electron configuration of magnesium (Mg) is 1s2 2s2 2p6 3s2. This means that the atom of magnesium has 12 electrons, with two in the first shell, two in the second shell, six in the third shell, and two in the fourth shell. Again, the super subscripts (2, 2, 6, 2) are the number of electrons in each orbital. Simply add up these numbers, which will give you 12. Now just look for the element on the periodic table with the atomic number of 12.
By understanding the basics of electron configuration, you can easily identify the atomic number of an element from its electron configuration. You can also use this knowledge to identify the element associated with a given electron configuration. With this information, you can start to understand the properties of different elements and their role in chemistry, physics, and biology.

What are Electron Configurations?
Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. For example, the electron configuration of sodium is 1s22s22p63s1. This notation is based on the Aufbau principle, which states that electrons fill orbitals in order of increasing energy.
Table of Electron Configurations
When n=4, the subshells correspond to l=0, l=1, l=2, and l=3 and are named the s, p, d, and f subshells, respectively. 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:
| Subshell | n | l | Max number of electrons |
|---|---|---|---|
| s | 1 | 0 | 2 |
| p | 2 | 1 | 6 |
| d | 3 | 2 | 10 |
| f | 4 | 3 | 14 |
Exceptions to the Aufbau Principle
It is important to note that there exist many exceptions to the Aufbau principle such as chromium and copper. In these cases, electrons are filled in orbitals with lower energy before those with higher energy. This is due to the presence of the so-called “inert pair effect”, which is caused by the repulsion between the electrons in the last occupied orbital and those in the next higher orbital.
In conclusion, the electron configuration 1s2 2s2 2p6 3s2 3p4 represents the ground state of an atom, and is determined by the Aufbau principle. There exist exceptions to this principle, such as chromium and copper, where electrons are filled in orbitals with lower energy before those with higher energy.

What are Electron Configurations?
The electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. For example, the electron configuration of sodium is 1s22s22p63s1.
However, the standard notation often yields lengthy electron configurations (especially for elements having a relatively large atomic number). To make the notation more convenient and understandable, an alternative notation known as the “noble gas core” notation is used. In this notation, the electrons are written in the order of their filling in the atomic orbitals, starting from the lowest energy level. The noble gas element that precedes the element of interest is written in the beginning of the configuration to indicate the core electrons. For example, the electron configuration for chlorine (Cl) can be written as [Ne]3s23p5.
