Give 1 characteristic for: Alkali Metals, Alkaline Earth Metals, Halogens, Neon Gases, and Hydrogen.
A few examples are... Alkali Metals: Soft, low density, 1+ charge, Not found free in nature Alkaline earth metals: 2+ charge, Hard, low density, very reactive Halogens: Bright coloured, not found naturally, all toxic, 1- charge Noble gases: non reactive, colourless, very low boiling point Hydrogen can either be 1+ or 1-, most common element in the universes, lowest of all known elements, colourless
