Answer :
The answer should be B because it just works better for the atom to just give on away and not two or three at once
The correct answer is option b. an atom with one valence electron.
The atom, which has only one atom in its valance cell, then the atom would tend to lose one electron to maintain a noble atom configuration and gain stability.
The atom having no valance electron, two valance electrons and three valance electrons would have less ionic tendency as compared to that of the atom with one valance electron.
