Notes

• Actinides and lanthanides are collectively known as "rare earth elements".
• Alkali metals, alkaline earth metals, transition metals, actinides, lanthanides, and poor metals are all collectively known as "metals".
• Halogens and noble gases are also non-metals.
• Atomic masses stated in square brackets, "[]", refer to that of the most stable isotope.
