Can someone explain to me step by step how to do E.) I'm so confused ! A friend told me I had to add the elements and see what equals 0, but so far none do and some are polyatomic ions and I don't know how to find the valence electrons for it
To be a covalent compound, that compound must be composed of nonmetals, I think among all the answers given in Q-E, PCl3 is the one most likely to be a covalent!
