Question

What is difference between Metals and Non-Metals ​

Answer 1

metals:

Metals are those substances that are hard and holds the property of thermal and electrical conductivity (except tungsten). These materials are lustrous in nature and thus polishing of such elements gives rise to a reflecting surface.

non metals:

Non-metals are materials that are soft and possess poor electrical and thermal conductivity. This means that non-metals restrict the flow of electric current through them. However, graphite stands here as an exception because it exhibits good electrical conductivity.
