Periodic Table VOCAB + FACTS

Alkali Metals

Group 1 (does not include H); Solid, soft, high melting point; Highly reactive with water

Alkaline Earth Metals

Group 2; Solid, shiny, high melting point; Reactive (less than group 1)

Transition Metals

Groups 3–12; Hard, malleable, good conductors; React slowly with water and acids

Metalloids

Groups 13–17 (B, Si, Ge, As, Sb, Te, Po, At); Shiny, brittle, semi-conductive; Some are toxic

Non-metals

Groups 14–18; Can be solid, liquid, or gas; Dull, poor conductors, brittle; Used in industrial and biological reactions

Halogens

Group 17; Solid, liquid, or gas; Highly reactive, found in acids, react with metals

Noble Gases (Inert Gases)

Group 18; Odourless, colourless gases; Non-reactive
