 ## Molecular Compounds
 - Are not made of ions, instead molecules
-- Shared pairof electrons -> `covalent bonds`
+- Shared pair of electrons -> `covalent bonds`
+- Lone pair of electrons are electrons that are not shared
+- Radicals are unpaired electrons, vefy reactive
+- Molecules have no charge
+- Atoms fill their valence shells to form molecules
+- Double bond between oxygen atoms in an oxygen molecule
