Selenium has 6 valence electrons
6 valence electrons
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.
Six valence electrons

There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
A barium atom has two valence electrons.
Atomic number= No. of electrons in the atom. Atomic no. of selenium=34. Therefore,selenium has 34 electrons in each of its atom.
A chlorine atom has 7 valence electrons.
