What are valence shell electrons? A. Electrons that are uncharged B. Electrons that are positively charged C. Electrons that are available for bonding D. Electrons that are attached to the nucleus

C. Electrons that are available for bonding

Explanation:

Valence Shell Electrons can be define as  electrons found in the outermost shell of an atom.

These are the electrons that participate in chemical reaction.

Using the  K L M  electronic configuration  for illustration;

Na (sodium) has 11 as its atomic number; the electronic configuration is  2, 8,  1

The last shell in a sodium atom only has 1 electron, hence we say the valence electron is 1.

This is the electron that is used in bond formation when Sodium atom reacts with other atoms of different element e.g chlorine.

C. Electrons that are available for bonding.
