What is the valence of selenium?
Understand the Problem
The question is asking for the valence of selenium, which refers to the combining capacity of the element in terms of electrons. We need to identify the typical oxidation states or valency that selenium exhibits in chemical compounds.
Answer
6 valence electrons
Selenium has 6 valence electrons.
Answer for screen readers
Selenium has 6 valence electrons.
More Information
Selenium belongs to group 16 of the periodic table. Elements in this group typically have 6 valence electrons and often gain or share two electrons to complete their outer shell.
Tips
A common mistake is confusing the number of valence electrons with the number of total electrons. The valence electrons are only those in the outermost shell.
