How many valence electrons does selenium have?

Question:- How many valence electrons does selenium have?

Answer: 6 valence electrons

Selenium is an element with atomic number 34, and thus it has 6 valence electrons. This element is classified under Group 16 (formerly known as Group VIA), the chalcogens. The electronic configuration of the selenium is [Ar] 3d10 4s2 4p4. High energy electrons or valence electrons are those in the outermost shell of an atom, for selenium these are the 4s and 4p orbitals. More precisely, the distribution of electrons is 2 in 4s orbital and 4 in 4p orbital making a total of 6 valence electrons. These valence electrons or the outer-shell electrons decide selenium’s chemistry and how this element will react. The element is responsible for the possibilities of covalent bonding and the participation in chemical reactions. The number of valence electrons is the most essential factor in determining how much a given element will react, the state it can borrow money to in the periodic table and the type of bond it can make in chemistry.
