An ionic compound is made up of a metal and a nonmetal. This eliminates answer choice A, C, and D because both of the elements listed are nonmetal.

Your correct answer is B) One atom of calcium and two atoms of chlorine. This is because calcium is a metal, and chlorine is a nonmetal.

Answer : The correct option is, (B) One atom of calcium and two atoms of chlorine.

Explanation :

Ionic compound : It is a compound in which the atoms are bonded through the ionic bond. The ionic bonds are formed between the one metal and one non-metal. It is formed by the complete transfer of electrons.

Covalent compound : It is a compound in which the atoms are covalently bonded. The covalent bonds are formed between two non-metals. The covalent bonds are formed by the equal sharing of the electrons.

From the given options, only option (B) pair of atoms will form an ionic compound because calcium is a metal and chlorine is a non-metal. While the other options will not form an ionic compound because the two atoms are non-metals.

Hence, the correct option is, (B) One atom of calcium and two atoms of chlorine.
