ovalent bond is formed betweenA A metal and a non metal B 2 metal C 2 non-metals D None of these

A covalent bond is formed between two non-metals. So, the correct answer is C. 2 non-metals.

Here's a step-by-step explanation:

1. A covalent bond is a type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons.

2. Metals tend to lose electrons to achieve a stable electron configuration. On the other hand, non-metals tend to gain or share electrons to achieve stability.

3. When two non-metals bond, they share electrons because neither atom is willing to donate electrons to the other. This sharing of electrons leads to the formation of a covalent bond.

4. Therefore, a covalent bond is typically formed between two non-metals.
