Answer 2

Answer:

Give differences between metallic elements and non-metallic elements and on their physical properties​

Explanation:

The difference between metals and non-metals is that metals are good conductors of heat and electricity whereas non-metals are bad conductors of heat and electricity. Other than that metals have properties like they are shiny, malleable, and ductile whereas non-metals are not shiny, ductile, or malleable.
