How could you identify that two elements have formed an ionic bond?
1) if one element has transferred valence electrons to another element’s valence shell, forming a cation and anion
2)if both of the elements involved are metals that will form cations through the transfer of valence electrons
3)if the elements share valence electrons with each other in the valence shell, forming a cation and anion
4) if both of the elements involved are nonmetals that will form anions through the sharing of valence electrons
