Question

What is a valence electron and why are they important to a chemist?

Answer 1

Answer:

Valence electrons are those electrons farthest away from the nucleus of an atom. They are important in chemistry because they are responsible for determining the chemical behavior of an atom. ... This means that all of the molecules which govern life-giving chemistry have carbon atoms as their principal component. please mark as branlist please

Answer 2

Answer:

An electron in the outer shell of an atom that can participate in bond formation is called a valence electron. They are important to a chemist because it determines the chemical behavior of an atom.

Explanation:

Valence electrons reside in the outermost shell of an atom. For a main-group element, a valence electron can exist only in the outermost electronic shell whereas, for a transition metal, a valence electron can also be in an inner shell. The presence of valence electron determines whether it can form bonds with other elements or how readily it can form bonds.
