6 valence electrons
Neutral selenium has 6 valence electrons.
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.
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
Selenium is Atominc number: 34 It has 6 Valence electrons Therefore you take 6 from 34: 28 core electrons

No, Selenium has 6 valence electrons while Bromine has 7. You can determine this because on the periodic table, Selenium is in Group VI while Bromine is in group VII.
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.
