Front

What is a covalent bond?

Back

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

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.

Front

What is a molecule?

Back

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