Electron configurations are an incredibly important concept in Chemistry, as they give us a way to understand the arrangement and behavior of electrons in different elements. A basic understanding of electron configurations helps us to understand the properties and behavior of different elements, and is a fundamental part of the Periodic Table.
The electron configuration of an element is expressed in a standard notation, where all electron-containing atomic subshells are arranged in a sequence. For example, the electron configuration of sodium is 1s22s22p63s1. But, for elements with larger atomic numbers, the electron configuration can become quite lengthy. In the case of the representative elements, the distinguishing electron will be in an ns or np subshell. This value of n, the principal quantum number for the distinguishing electron, can be determined by counting down from the top of the periodic table.
In particular, the electron configuration 1s22s22p63s23p64s13d10 corresponds to the element Pr, or praseodymium. The atoms of elements in the same vertical column of the periodic table will also have similar electron configurations. For example, the alkaline-earth elements (Group IIA) all have the same electron configuration, 1s22s22p63s2.
So, electron configurations are an incredibly useful tool in understanding the behavior of different elements, and how they interact with one another. Knowing the electron configuration of an element can help us to better understand its reactivity, and can provide insight into its physical and chemical properties. With a better understanding of electron configurations, we can better understand the structure and behavior of elements and the Periodic Table.
Which element corresponds to the electron configuration 1s22s22p63s23p64s13d10?
When it comes to understanding elements and their electron configurations, it can be helpful to refer to the periodic table. Electron configurations are the arrangement of electrons around the nucleus of an atom, and they can be used to identify which element an atom belongs to. The electron configuration 1s22s22p63s23p64s13d10 corresponds to the element Praseodymium, a rare earth element located in the 5th period of the periodic table.
What are Electron Configurations?
Electron configurations are used to describe the arrangement of electrons around the nucleus of an atom. These configurations are written using a standard notation which specifies the number of electrons in each of the atomic orbitals. For example, the electron configuration of sodium is written as 1s22s22p63s1. However, the standard notation often yields lengthy electron configurations, especially for elements with a large atomic number.
How to Identify the Element from an Electron Configuration?
In order to identify the element from a given electron configuration, it is helpful to refer to the periodic table. As a general rule, the distinguishing electron will be in an ns or np subshell. The value of n, the principal quantum number for the distinguishing electron, can be quickly determined by counting down from the top of the periodic table. For example, iodine is a representative element in the fifth period, so the distinguishing electron must occupy either the 5s or 5p subshell.
The electron configuration 1s22s22p63s23p64s13d10 corresponds to the element Praseodymium, a rare earth element located in the 5th period of the periodic table. This element is a soft, silvery white metal which is highly reactive and flammable in air.
The Relationship between Electron Configuration and the Periodic Table
It’s important to note that atoms of elements in the same vertical column of the periodic table have similar electron configurations. For example, the alkaline-earth elements (group IIA) all have the same electron configuration: 1s22s22p63s2. This is because the outermost electrons of these elements occupy the same subshells.
Electron configuration is an important concept in chemistry which can be used to identify elements and their properties. By referring to the periodic table, it is possible to quickly determine the element associated with a given electron configuration.

Why are Electron Configurations Important?
Electron configurations are important for a variety of reasons. For example, they can be used to determine the valency of an element (the number of electrons it has available to form chemical bonds). They can also be used to predict the properties of a group of elements—elements with similar electron configurations tend to exhibit similar properties. Finally, electron configurations are helpful for interpreting atomic spectra.

What are Electron Configurations?
Electron configurations describe how electrons are distributed in atomic orbitals. According to the standard notation, 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). For example, the electron configuration of chromium is 1s22s22p63s23p63d44s2. Note that when writing the electron configuration for an atom like Cr, the 3d is usually written before the 4s. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written (here is an explanation why).
Half-filled and Fully Filled Subshells Have Extra Stability
Half-filled and fully filled subshells have extra stability. This means that when an atom has a subshell that is half-filled or completely filled, the electrons in that subshell are less likely to be involved in chemical reactions. This is why elements with similar electron configurations tend to exhibit similar properties.
Therefore, the element with the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 quizlet is chromium (Cr). This electron configuration is associated with extra stability, meaning that atoms of this element are less likely to be involved in chemical reactions. This is why chromium and other elements with similar electron configurations tend to exhibit similar properties.

For example, if two electrons are filled in the ‘s’ subshell of the first shell, the resulting notation is ‘1s2’.
