What is the complete ground state electron configuration for the selenium atom?

Se
1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰3p⁴

You can do it just follow the periodic table
1)groups 1 and 2 give s-electrons , and number of the level equals number of the period
2)groups from 13 to 18 give p-electrons, and number of the level equals number of the period
3) groups from 3 to 12 give d-electrons and level one less than number of the period

The complete ground state electron configuration for the selenium atom is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁴.

The ground state electron configuration is the arrangement of electrons around the nucleus of an atom with lower energy levels. Selenium has an atomic number of 34, which means it has 34 protons (positive charges). Since it is electrically neutral, it also has 34 electrons (negative charges).

The order in which electrons are arranged is explained by the Aufbau principle, which states that in the ground state of an atom or ion, electrons fill subshells of the lowest available energy, then they fill subshells of higher energy. The easiest way to know this order is through a picture such as the attached, with shows the diagonal rule. We start filling from the top right to the bottom left, following the diagonal. With this in mind, the electron configuration of Se is:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁴
