Question

what is difference between metals and non metals​

Answer 1

1. The natural elements that are hard, shiny, opaque and dense are metals. The chemical substances that are soft, non-shiny, transparent and brittle, are non-metals.
2. 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.Metals have a crystalline structure, whereas non-metals possess amorphic structure.

3. At room temperature, metals are usually solid, except mercury and gallium which are in the liquid state. Conversely, non-metals can be found in solid or gaseous form, except Bromine which is the only non-metal that is present in liquid form.

4. Density is the ratio of mass to volume; metals have a higher density as compared to non-metals.

5. Metals have a crystalline structure, whereas non-metals possess amorphic structure.

Answer 2

Answer:

metals are good conductor of heat and electricity and non metals are bad conductor of electricity
