Electron configuration is the arrangement of electrons in an atom. There are four blocks in the Periodic Table: S, P, D, F. Block S is groups 1 and 2. Block P is groups 13-18. Block D is groups 3-12. And block F is the lanthanides and actinides. There are several exceptions, for example He is considered part of S block even though it is over group 18. Here are some examples:
He - 1S2
Al - 1S22S22P1
Ni - 1S22S22P63S23P64D8
Shorthand form uses the noble gases (group 18). Whatever element you are using, go to the closest noble gas. For example:
Ca - [Ar] 4S2
The electron configuration (short form) of fermium is: [Rn]5f127s2.
The long form electron configuration for carbon is simply 1s2 2s2 2p2. The noble gas shortcut electron configuration for C is [He] 2s2 2p2.
The element radium (atomic number 88) has the long term electron configuration 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p64f14 5d10 6s2 6p6 7s2 The electron configuration (short form) of radium is [Rn]7s2. It's configuration is also 2.8.18.32.18.8.2
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
[Xe] 6s1
The electron configuration (short form) of fermium is: [Rn]5f127s2.

The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The electron configuration, in standard form, is [Ne] 3s2 3p6
It is a shorthand form of the electronic configuration. A typical example is Potassium Full electronic configuration 1s2 2s2 2p6 3s2 3p6 4s1 Noble gas notation [Ar] 4s1
The long form electron configuration for carbon is simply 1s2 2s2 2p2. The noble gas shortcut electron configuration for C is [He] 2s2 2p2.
The standard electron configuration form of boron is 1s2 2s2 2p1. The noble gas form is [He] 2s2 2p1.
They achieve the electron configuration of a noble gas.
The element radium (atomic number 88) has the long term electron configuration 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p64f14 5d10 6s2 6p6 7s2 The electron configuration (short form) of radium is [Rn]7s2. It's configuration is also 2.8.18.32.18.8.2
The electron configuration of oxygen (atomic number 8) is 1s2 2s2 2p4The noble gas form is [He] 2s22p41s2 2s2 2p4
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
Ar is Argon and Ar 4s1 is the short form of the electron configuration 1s2 2s2 2s6 3s2 3s6 4s1. It means add 4s1 to the electron configuration of Argon to get the electron configuration of potassium.
