Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

How are covalent bonds formed?

Back

Covalent bonds are formed when two atoms share electrons.

Front

What is the difference between a single covalent bond and a double covalent bond?

Back

The difference is the number of electron pairs being shared; a single bond shares one pair, while a double bond shares two pairs.

What is the strength comparison between single and double covalent bonds?

Back

Double covalent bonds are generally stronger than single covalent bonds.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.
