Question

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

Now think !
What are common ionic bonds?
for example
NaCl table salt
Na is +1, gave up the one electron it had in the outer shell
Cl is -1 , grabbed an extra electron from the Na to fill its outer shell

+2 and even more can form ionic bonds but +1 and - 1 are the big winners

Atoms like Carbon with half full shells often form covalent bonds sharing its outer electrons. They do not do ionic.

Atoms with NO valence electrons just plain do not like to bond at all. That is why "noble gases" are called that. Like Helium does not even form an He2 gas molecule like Hydrogen forms H2 or Oxygen forms O2
