Legend for category color

Background color shows subcategory in the metal–nonmetal range: លោហៈ Metalloid អលោហៈ Unknown chemical properties អាល់កាឡាំង Alkaline earth metal Lan­thanide Actinide Transition metal Other metal Polyatomic nonmetal Diatomic nonmetal ឧស្ម័នកំរ

Antimatter atoms are denoted by a bar above the symbol for their matter counterpart, so e.g. H is the symbol for antihydrogen.
