What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

What is a molecule?

Back

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

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their outer shell.

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between atoms, resulting in a molecule with a slight charge.
