Selenium is a group 16 element. It has 6 electrons in its valence shell and simply on that basis would be predicted to be divalent. and that is found to be true with compounds such as H2Se, However like sulfur it is capable of other valencies.
It can be tetravalent, examples are SeO2 (which is chain polymer) and SeF4.
It can also be hexavalent in SeF6, an octahedral molecular compound.
And it can appear to be monovalent in for example Se2Cl2 which is actually Cl-Se-Se-Cl.

What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
How many valence electrons does neutral selenium have?
Neutral selenium has 6 valence electrons.
What is the valence electron configuration of selenium?
The valence electron configuration of selenium is 4s2 4p4, meaning it has 6 valence electrons.
How many valence electrons in selenium?
Selenium has 6 valence electrons. It belongs to group 16 of the periodic table, so it has 6 electrons in its outermost energy level.
How many valence electron have selenium?
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.
