Question

Which of the following are likely to form a covalent bond ? Silver atoms , argon atoms, sodium and chlorine atoms, carbon and chlorine atoms

Answer 1

Answer:

Carbon and Chlorine are likely to form a covalent bond.

Explanation:

Covalent bond is formed when two atoms share their electrons to complete their octet and achieve inert configuration. Covalent bonds are formed  between two non metals with similar electronegativities that are unable to fully donate electrons.

Generally, two nonmetals form covalent bond, a metal and a nonmetal form ionic bond and two metals form metallic bonds.

1. Silver is a metal and hence form metallic bond with other Silver atom.
2. Argon is an inert elements hence does not form compound easily.
3. Sodium and Chlorine being Alkali metal and non metal, form ionic compound.
4. Carbon and Chlorine are two nonmetals and hence are more likely to form a covalent bond.
