Question

How do the following physical properties differ for metals and

non – metals?

a)Sonority b) Conductivity of heat

c) Conductivity of electricity d) Hardness​

Answer 1

a) metals produce sound when stuck with any object but their is no sound produced by non-metals.

b) Thermal conductivity measures the ability of a metal to conduct heat. This property varies across different types of metal and is important to consider in applications where high operating temperatures are common. heat conductivity in nonmetals is mainly due to lattice vibrations (phonons). ... Thus, the thermal conductivity of nonmetals is approximately constant at high temperatures.

d) Most metals are hard, except sodium. whereas Most non-metals are soft, except diamond.
