CHEMICAL PROPERTIES OF METALS
Metals and non-metals differ from each other in their chemical properties.
1) REACTION WITH OXYGEN
hold a magnesium ribbon with pair of tongs and ignite it . Magnesium ribbon burns with a bright white light and forms a white powder. This white powder formed is Magnesium oxide.
2Mg (s) + O2 (g) = 2MgO (s)
(Magnesium) (Oxygen) (Mag. Oxide)
2) REACTION WITH WATER
Mg (s) + 2H2O (L) = Mg (OH2) (aq)
+ H2 (g)
