Solution

Metals Nonmetals
Most of the metals are malleable and ductile.
Non-metals are brittle and non-malleable and lack ductility.
2. Most of the metals are sonorous. 2. Non-metals are not sonorous
3. The metals offer very little resistance to the flow of electric current and hence show high electrical conductivity. They give away their outer shell electrons. 3. Non-metals do not have free electrons like metals and hence they do not conduct heat and electricity. They usually accept electrons in their outer shell.
4. Most of the metals have high melting points and boiling points. 4. Most of the non-metals have a low melting points and boiling points.
