Tin is a chemical element wi seembol Sn (for Laitin: stannum) an atomic nummer 50. It is a main group metal in group 14 o the periodic table. Tin shaws chemical seemilarity tae baith neighborin group-14 elements, germanium an leid, an haes twa possible oxidation states, +2 an the slichtly mair stable +4. Tin is the 49t maist abundant element an haes, wi 10 stable isotopes, the lairgest nummer o stable isotopes in the periodic table. Tin is obtained chiefly frae the mineral cassiterite, whaur it occurs as tin dioxide, SnO2.
