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.
Selenium has 6 electrons in its outermost shell.
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
Selenium has 6 valence electrons. It belongs to group 16 of the periodic table, so it has 6 electrons in its outermost energy level.
Neutral selenium has 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.

Neutral selenium has 6 valence electrons.
Selenium has 6 valence 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.

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.
Selenium and sulfur are both elements in the same group on the periodic table and share similar chemical properties. They can both form compounds with similar structures, and both have important roles in biological systems. However, selenium is less abundant in nature compared to sulfur.
