Question
Compare the properties of a typical metal and a non- metal on the basis of the following:
(a) electronic configuration
(b) nature of oxides
(c) oxidizing or reducing action
(d) conductivity of heat and electricity
Solution
Property | Metal | Non-metal |
Electronic Configuration | Usually have 1, 2 or 3 electrons in valence shell . | Usually have 5, 6 or 7 electrons in the valence shell. |
Nature of oxides | They generally form basic oxides some of which are amphoteric as Al2O3 | Generally form acidic oxides (CO2, SO2). Some oxides are neutral as NO N2O. |
Oxidizing or reducing action | Reducing agents | Oxidizing agents |
Conductivity of heat and electricity | Generally they are Good conductors of both heat and electricity. | Generally they are Poor conductors of heat and non conductors of electricity. |
