Chlorine (Cl) is a nonmetal and has a high electronegativity. It tends to gain one electron to achieve a stable octet configuration. Therefore, it will form ionic bonds with elements that are metals and readily lose electrons.

Here are some examples of metals that would bond ionically with chlorine:

* Sodium (Na): Sodium is in group 1, meaning it has one valence electron that it readily loses to form a +1 ion (Na+). This forms sodium chloride (NaCl), commonly known as table salt.

* Potassium (K): Similar to sodium, potassium is also in group 1 and forms a +1 ion (K+). This forms potassium chloride (KCl), used in fertilizer and medicine.

* Magnesium (Mg): Magnesium is in group 2 and readily loses two electrons to form a +2 ion (Mg2+). This forms magnesium chloride (MgCl2), used in de-icing agents and as a drying agent.

* Calcium (Ca): Similar to magnesium, calcium is in group 2 and forms a +2 ion (Ca2+). This forms calcium chloride (CaCl2), used as a drying agent and in road salt.

In general, metals from groups 1 and 2, as well as some transition metals, tend to form ionic bonds with chlorine.
