Liquid to gas: solid to gas, solid dissolving into another liquid substance. Periodic table: atoms are aligned in a group with similar properties. August 30, 2017: elements combine to make compounds, elements come together to make compounds, compounds are more stable than the pure elements, compounds are formed in chemical bonds, how the electrons are shared among atoms.
