Chemical Properties of Metals and Non Metals
Metallic oxides are basic in nature.They frequently dissolve in dilute mineral acid to liberate hydrogen gas.They either do not combine with hydrogen and form non volatile hydrides.Their chlorides are not hydrolyzed by water. Chemical Properties of Metals and Non Metals are considered during their reaction with other compounds.
Non metallic oxides are acidic in nature.They does not dissolve in dilute mineral acids.They form stable compound with hydrogen.Their chlorides are completely hydrolyzed by water.
Reaction of metals with oxygen:
Reaction of Iron metal with oxygen:
When iron reacts with moist air, it forms rust. Rust is iron oxide. Articles made of iron, such as grills, fencing, etc. are get rusted because of reaction with moist air.Rust is reddish brown in colour and is iron oxide.
Reaction of Magnesium metal with oxygen:
Reaction of Non-metals with oxygen:
Non-metal forms their oxide when reacts with oxygen.
Reaction of sulphur with oxygen
Reaction of carbon with oxygen
When carbon is burnt in air, it forms carbon dioxide. You can observe that when coal (carbon) is burnt it forms smoke, which contains carbon dioxide.
Reaction of Metals and Non-metals with water:
Reaction of sodium metal with water:
Reaction of potassium with water:
