4s2 4p4
The element with a valence electron configuration of 4s²4p⁴ is selenium (Se). It is located in group 16 of the periodic table and is known for its various allotropes and applications in electronics and glassmaking. Selenium is a nonmetal and is essential in small amounts for certain biological functions.
Selenium has 6 electrons in its outermost shell.
6. If you look at the electron configuration of Selenium, it is [Ar]3d^10 4s^2 4p^4, meaning 10 electrons are located in the 3rd shell, and a total of 6 are located in the 4th shell, the highest energy shell. The electrons in the 4s and 4p shells combined are the valence electrons, meaning there are 6 valence electrons on Selenium.
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.

Six valence electrons
The electron configuration of selenium is [Ar]3d10.4s2.4p4.
Se2- 1s22s22p63s23p64s23d104p6
Selenium needs to gain two electrons to achieve a stable electron configuration. By gaining two electrons, selenium will have a complete outer energy level (valence shell), which is the most stable configuration for an atom.
The element with a valence electron configuration of 2s2 is beryllium. Beryllium has 4 electrons, with 2 in the 2s subshell, which makes it have a valence electron configuration of 2s2.
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.
The electron configuration of phosphorus is [Ne]3s2.3p3.
