4. Ionic bonds form between metal and nonmetal elements.5. When ionic bonds are formed, the valence electrons are transferred from the metal atom to the nonmetal atom.6. Cations are positive because they have lost one or more electrons, resulting in a net positive charge.7. Anions are negative because they have gained one or more electrons, resulting in a net negative charge.8. No, ionic formulas like NaCl do not have a charge even though they are made from ions. This is because the positive and negative charges of the ions balance each other out, resulting in a neutral compound.9. In an ionic formula, a subscript indicates the number of atoms of that element present in the compound. For example, in , the subscript 2 indicates that there are two chlorine atoms for every one barium atom.
