Which is most likely to be part of an ionic bond?
A) an atom with no valence electrons
B) an atom with one valence electron
C) an atom with two valence electrons
D) an atom with three valence electrons

Answer 1

ionic compounds are formed between elements which have a very high difference in electronegativity. Electronegativity is the property of an element to pull electrons. When the difference electronegativity is high (i forgot the specific number) the more electronegative atom completely takes away an electron from the less electronegative atom. That generally applies to metal (less electroneg) + non metal (more electroneg) pairs of elements.

With that said, the most likely pairs of elements to form ionic compounds are
