What conclusions can you draw concerning the structures of species containing the same number of atoms and the same number of valence electrons? (Select all that apply.)

Only molecules/ions that have the same number of atoms will have similar Lewis structures. Only molecules/ions that have the same number of valence electrons will have similar Lewis structures. Molecules/ions that have the same number of valence electrons and the same number of atoms will have similar Lewis structures. Molecules/ions that have the same number of valence electrons but not the same number of atoms will have similar Lewis structures. Molecules/ions that have the same number of atoms but not the same number of valence electrons will have similar Lewis structures.
