What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What is a single bond?

Back

A bond that shares one pair of electrons between two atoms.

Front

Back

A bond that shares two pairs of electrons between two atoms.

Front

What are valence electrons?

Back
