Front

How are atoms held together in covalent bonds?

Back

By sharing electrons.

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 a polar covalent bond?

Back

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

Front

What is a non-polar covalent bond?

Back

A non-polar covalent bond is a bond where electrons are shared equally between two atoms.
