4. Ionic bonds form between metal and nonmetal elements.<br />5. When ionic bonds are formed, the valence electrons are transferred from the metal atom to the nonmetal atom.<br />6. Cations are positive because they have lost one or more electrons, resulting in a net positive charge.<br />7. Anions are negative because they have gained one or more electrons, resulting in a net negative charge.<br />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.<br />9. In an ionic formula, a subscript indicates the number of atoms of that element present in the compound. For example, in $BaCl_{2}$, the subscript 2 indicates that there are two chlorine atoms for every one barium atom.
