The valence electron configuration of selenium is 4s2 4p4, meaning it has 6 valence electrons.
Selenium has 6 electrons in its outermost shell.
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
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.
Two- Since it has six valence electrons, it can form two covalent bonds, making the valence two. If it is easier to think about it this way, eight valence electrons would stabilize the element. Eight minus six is two, giving us the same answer as before.

Oxygen has six valence electrons.
A neutral oxygen atom has six valence electrons.
Sulfur has 6 valence electrons.
Elements in group 16 of the periodic table, also known as the oxygen group, have six valence electrons. This group includes elements such as oxygen, sulfur, and selenium. These elements typically form -2 ions in chemical reactions.
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
