Chemical Properties of Metals
Metals are electrically positive in nature, and have a tendency to give up electrons and form cations. Therefore, those metals react quickly non-metals oxygen, hydrogen, chlorine, sulfur etc.
Reaction of Metals with Oxygen-
All metals react with oxygen to form a metal oxides. For example aluminum oxide, reacting with aluminum, reacts with copper to produce copper oxide Metal oxides are insoluble in water.
Reaction of Metals with Water-
Metals like sodium, potassium and magnesium react with water to form metal hydroxides and produce hydrogen.
Reaction of Metals with Acid-
Metals react with dilute acid to produce the corresponding salts and hydrogen gases.
Reaction of Metals with Solution of other Metal salts-
Reactive metal displaces less reactive metal from its solution or dissolved state of its compound.
Color of Metal Flames-
Alkaline metals and their salts produce characteristic colors in the flame.
