The compounds formed in this way are ions, rather than molecules, because the bonded atoms change their amount of electrons and thus become electrically unbalanced. Molecules consisting of nonmetals are joined by covalent bonds; their electrons are shared by pairs of atoms, not transferred, so the bond between them tends to be very tight.
Molecules and compounds. When atoms of the same element combine, they form molecules. Compounds are formed when molecules of two or more atoms are joined together. For example, because water is a combination of two different elements (hydrogen and oxygen), it.
