Question

distinguish between metals and nonmetals on the basis of
(a) nature of oxides
(b) oxidising and reducing agent​

Answer 1

Answer:

The chemical substances that are soft, non-shiny, transparent and brittle, are non-metals. Metals are electropositive in nature as they easily lose electrons, so they are reducing agents. On the contrary, Non-metals are electronegative because they gain electrons and thus they are oxidising agents.

Difference Between Metals And Nonmetals

A reactivity series is a vital tool for chemists. It helps us to understand the properties of metals and the differences between them.

Metals                                                                                 Nonmetals

These are solids at room                                   These exist in all three states

temperature except mercury

             

These are very hard except sodium            These are soft except diamond

These are malleable and ductile                      These are brittle and can be

                                                                               breakdown into pieces

These are shiny                                                 These are non-lustrous  

                                                                                         except iodine

Electropositive in nature                               Electronegative in nature

Have high densities                                             Have low densities
