Metal is an element that readily produces positive ions (cations) and has metallic bonds to form complexes. Monovalent metal ions form weak and unstable complexes, while polyvalent metals form rapidly and quantitatively. Let’s see how familiar are you with metals. Identify which among the following metals/ions are polyvalent or monovalent.  Sodium Magnesium Copper Lithium Zinc Aluminum Silver Tin Potassium Strontium Calcium Barium Cesium Mercury Cadmium
