\(\boxed{\left( 1 \right){\text{ calcium}}}\) 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).
