tion of the positive calcium ion and the negative bromide ion. Models should show that the calcium atom loses two electrons, forming Ca2, and that bromine gains one electron, forming Br. The models should also show the addition of energy to form the calcium

why do nonmetals form covalent bonds - The Bougie …

Nonmetal atoms frequently form covalent bonds with other nonmetal atoms. The only pure covalent bonds occur between identical atoms. However, compared to metals, nonmetal compounds do have relatively low melting.boiling points. This is because nonmetals differ widely in interatomic and intermolecular bonding strengths.
