Question

A ____________________________ is always a molecule, but a _______________________is not always a compound.

Answer 1

A compound is always a molecule, but a molecule is not always a compound

This is because a molecule is made up of multiple atoms, but they can be made of multiple of only one type of atom (ex
`O_(2)`)

This differs from a compound which is made up of multiple different types of atoms (ex
`NaCl` or
`H_(2) O`)
