Question

Which pair of elements will form a covalent bond?
O potassium and chlorine
O carbon and sulfur
O aluminum and chlorine
O
lithium and oxygen

Answer 1

The answer is most likely carbon and sulfur since both of those are nonmetal covalent elements.

Answer 2

Answer: Option (b) is the correct answer.

Explanation:

A covalent bond is defined as the bond formed between the two atoms due to sharing of electrons.

A covalent bond is always formed between non-metals.

For example, carbon and sulfur are both non-metals and when they chemically combine together they form $CS_{2}$ which is a covalent compound.

Thus, we can conclude that out of the given options carbon and sulfur is the pair of elements that will form a covalent bond.
