Question

compare the metals and non-metals on the basis of their reaction with air.

Answer 1

Answer:

Generally, metals are good conductors of heat and electricity but non-metals are poor conductors. On burning, metals react with oxygen to produce metal oxides which are basic in nature. Non-metals react with oxygen to produce non- metallic oxides which are acidic in nature.

Answer 2

Metals tend to be strong and conductive, and have high melting points. However, like nonmetals, their forms occur as a distinct combination of electrons, protons and neutrons. All elements, metal or otherwise, can change state or react.
