Covalent bonds exist between two nonmetal elements while ionic bonds exist between a metal and a nonmetal element. In this case, oxygen is a nonmetal and in order to create an ionic bond, the other substance should be a metal. The answer therefore to this problem is calcium.

$\boxed{\left( 1 \right){\text{ calcium}}}$ reacts with oxygen to form ionic bonds.

Further Explanation:

Covalent bonds are the types of bonds that involve the sharing of electrons between the bonded atoms. This bond is usually formed between two or more non-metals.

Ionic bonds are the chemical bonds that involve the transference of electrons from one atom to another. These bonds are generally formed between metals and non-metals. In these types of bonds, ions are formed by the atoms. Cations are formed by the loss of electrons and anions result from the gain of electrons.

Oxygen is a non-metal. In order to form an ionic bond with oxygen, the other element has to be a metal.

Hydrogen, chlorine, and nitrogen are non-metals so these can form covalent bonds with oxygen. But calcium is a metal and it forms ionic bonds with oxygen. Calcium loses two electrons to form ${\text{C}}{{\text{a}}^{2 + }}$ and these electrons are gained by oxygen, resulting in the formation of ${{\text{O}}^{2 - }}$ . The attraction between ${\text{C}}{{\text{a}}^{2 + }}$ and ${{\text{O}}^{2 - }}$ is an ionic bond and the resulting compound is CaO (For structure, refer to the attached image).
