In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6 , meaning that the 1s, 2s, and 2p subshells are occupied by two, two, and six ...
Electron configurations describe where electrons are located around the nucleus of an atom. For example, the electron configuration of lithium, 1s²2s¹, tells us that lithium has two electrons in the 1s subshell and one electron in the 2s subshell. Created by Sal Khan.

Electron configurations are a simple way of writing down the locations of all of the electrons in an atom. As we know, the positively-charged protons in the nucleus of an atom tend to attract negatively-charged electrons.
- For the electron configuration table, how you can fill 10 electrons in 5p orbital?I think they updated it, since I can't find any 5p10 in this article
- In the electronic configuration diagram, isn't a p orbital only supposed to have 6, and not 10? In t...I don't know where you are seeing this, but you are correct in that a p orbital can fill up a max of 6 electrons (in all energy levels).
- what is the use of n,l,ms, and ml pls helpn,l,ml and ms kind of work as a coordinating system for electrons. n, the principal quantum number, tells you in which main energy shell it's in. n...
- Should orbital 5p be able to have 10 electrons in it or is it only 6? Im referring to the electron c...Should be 6 electrons because p orbitals could only have a maximum of 6
- In the second paragraph, it says that the protons (positive) attract the electrons (negative). But l...I think your magnet example actually answers your question. I think to clarify, they meant that electrons attract protons, but electrons repel elec...
- Why are only noble gases used to shorten the electronic configuration ,why not other elements?It's just common convention to reduce the size of the Electronic configurations. Scientists could have picked any group of elements, but the noble...
To write the electron configuration of an atom, identify the energy level of interest and write the number of electrons in the energy level as its superscript as follows: 1s 2. This is the electron configuration of helium; it denotes a full s orbital.
- Figure \\(\\PageIndex{1}\\): A Bhor's model can be used to diagram the location of electrons in each energy shell for an atom. Notice that protons go in the nucleus of the atom and electrons are drawn on orbits surrounding the nucleus.

Jan 30, 2023 · To help describe the appropriate notation for electron configuration, it is best to do so through example. For this example, we will use the iodine atom. There are two ways in which electron configuration can be written: I: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 5. or.
The arrangement of electrons in the orbitals of an atom is called the electron configuration of the atom. We describe an electron configuration with a symbol that contains three pieces of information ( Figure 6.25 ):
