Selenium: [Ar] 3d10 4s2 4p4 or 2, 8, 18, 6
Phosphorus: [Ar] 3d10 4s2 4p3 or 2, 8, 18, 5
The noble gas electron configuration of selenium is [Ar] 3d^10 4s^2 4p^4 and for phosphorus is [Ne] 3s^2 3p^3. These configurations indicate how the electrons are arranged in the outermost energy levels of the atoms, resembling the stable electron configurations of noble gases.
The valence electron configuration of selenium is 4s2 4p4, meaning it has 6 valence electrons.
Se2- 1s22s22p63s23p64s23d104p6
The electron configuration of selenium (Se) is [Ar] 3d10 4s2 4p4. To form a 2- ion, two electrons will be removed from the outermost shell, which is the 4p subshell. Therefore, the electron configuration of Se2- is [Ar] 3d10 4s2.

Krypton has the same electron configuration as phosphorus in a PCl3 molecule. Both have the electron configuration of [Ne] 3s^2 3p^3.
The noble gas electron configuration of Phosphorus is [Ne] 3s2 3p3
The 3p1 electron configuration belongs to phosphorus with the electron configuration 1s2 2s2 2p6 3s2 3p1. This means that phosphorus has 15 electrons, with the last electron occupying the 3p subshell.
Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
Phosphorus has an electron configuration of 1s2 2s2 2p6 3s2 3p3. Another way to write that is [Ne] 3s2 3p3. The [Ne] represents the fact that the beginning of phosphorus' electron configuration is the same as Neon's.
