1. Reactions with Air (Oxygen) Most metals will react with air to form a metal oxide (these are either basic or amphoteric). The most reactive metals like potassium, sodium and magnesium will burn with a very bright flame and will tarnish quickly in open air. Moderately reactive metals such as magnesium, aluminium, zinc and iron burn in strong
