There are many differences between metals and non metals.
if we have two solid samples of non metal and metal of same volume then we can check for differences by the following point
a) metal will appear lustrous while non metal must be dull
b) metal may be sonorous while non metals are generally not
c) metals are generally more denser than non metals so out of the same volume of two samples, the mass of metal solid will be more as compared to mass of non metal solid sample.
