Differentiate between metal and non-metal on the basis of their chemical properties.

AcademicChemistryNCERTClass 10

The difference between metals and non-metals are:
Metals Non-metals
(i) Metals form basic oxides or amphoteric oxides. (i) Non-metals form acidic or neutral oxides.
(ii) Metals replace hydrogen from acids and form salts (ii) Non-metals do not replace hydrogen from acids.
(iii) With chlorine, metals form chlorides which are electrovalent. (iii) With chlorine, non-metals form chlorides which are covalent.
(iv) With hydrogen few metals form hydrides which are electrovalent. (iv) With hydrogen, non-metals form many stable hydrides which are covalent.

[Extra information:  Some properties of metals are given below:
  1. The density of metals is usually high.
  2. Metals are malleable and ductile.
  3. Metals form an alloy with other metals or non-metals.
  4. Some metals react with air and corrode. For e.g. Iron.
  5. Metals are good conductors of heat and electricity. Lead is an exception.
  6. Generally, metals are in a solid-state at room temperature. Except for Mercury. Mercury is in a liquid state.]
