Question

1. Compare metals and non metals based on their physical properties answer in brief

Answer 1

Answer:

They have high electronegativities. Nonmetals are insulators which means that they're poor conductors of electricity. They are dull, they do not have lustre like metals. Nonmetals are poor conductors of heat.

Some of the differences between physical properties of metals and non-metals : <> Lustrous : Metals have lustrous property where as nonmetals don't have this property . <> Sonorous : Metals produce sounds but not non metals. ... <> High Melting and boiling points will be found in metals but not in nonmetals.

Answer 2

Answer:

Comparison Of Chemical Properties Of Metals And Non-metals

Non-metals have no reaction with water. Metals react with oxygen to form basic oxides. Zn and Al form amphoteric oxides which show the properties of both acidic and basic oxides. ... Non-metals react with oxygen to form oxides.
