What happens to valence electrons when a metal and a nonmetal form an ionic bond ?

the metal becomes a cat-ion when it gives one or more electrons to the nonmetal (which becomes an an-ion).

the metal shares one or more electrons with the nonmetal.

the metal destroys an electron to make a bond with a nonmetal

the nonmetal creates an electron to make it more negative

What happens to valence electrons when a nonmetal and another nonmetal form an covalent bond ?

the nonmetal shares one or more electrons with the other nonmetal.

one nonmetal becomes a cat-ion when it gives one or more electrons to the other nonmetal (which becomes an an-ion).

the nonmetal takes an electron from a metal to make a bond with a nonmetal

the nonmetal gives an electron to make the other nonmetal more negative
