Question

the electrons available to be lost, gained, or shared when atoms form molecules are call
a. ions
b. d electrons
c. valence electrons
d. electron clouds

Explanation:

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding (losing, gaining, or sharing) when atoms form molecules. Ions are charged atoms or molecules. D - electrons are a type of electron in an atom's sub - shell but not the general term for bonding electrons. Electron clouds represent the probability of finding an electron in a region around the nucleus, not the electrons involved in bonding specifically.

Answer:

C. valence electrons
