Question

what are valence electrons?​

Answer 1

Answer:

In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Answer 2

heya, buddy !!

➲ The Electrons present in the outermost shell which take part in chemical reactions are called valence eletrons. Like sodium electronic configuration is (2,8,1) but when it combines with any element then it has the tendency to lose its one.

➦ We know that, valence electron can exist in the inner shell of a transition metal.An atom consisting of a closed shell of valence electrons will usually be chemically inert.
