Detailed explanation-1: -A covalent bond is formed between two non-metals. The sharing of electron pair takes place between their atoms and a covalent bond is formed. Q. An ionic bond is formed when a non-metal and a metal form a bond by transferring electrons.

Detailed explanation-2: -Covalent bonding generally happens between nonmetals. Covalent bonding is the type of bond that holds together the atoms within a polyatomic ion. It takes two electrons to make a covalent bond, one from each bonding atom. Lewis dot structures are one way to represent how atoms form covalent bonds.

Detailed explanation-3: -In general, covalent bonds form between nonmetals, ionic bonds form between metals and nonmetals, and metallic bonds form between metals.

Detailed explanation-4: -Covalent bonds form when two or more nonmetals combine. For example, both hydrogen and oxygen are nonmetals, and when they combine to make water, they do so by forming covalent bonds.

Detailed explanation-5: -Hence, a bond that is formed by the sharing of electrons between non-metals is called a covalent bond.
