which statement describes the difference between a metallic bond and a hydrogen bond?
a. A metallic bond forms when two polar molecules are attracted to each other, while a hydrogen bond forms between positive ions and freely moving electrons surrounding them.
b. A metallic bond forms between positive ions and freely moving electrons surrounding them, while a hydrogen bond forms when two atoms share valence electrons.
c. A metallic bond forms between positive ions and freely moving electrons surrounding them, while a hydrogen bond forms when two polar molecules are attracted to each other
d. A metallic bond forms when two nonpolar molecules are attracted to each other, while a hydrogen bond forms between two atoms that can share a pair of valence electrons.
