Answers
Metals:
Metals are usually good conductors of heat and electricity.
They are hard, opaque, shiny, lustrous and malleable and ductile.
Metals usually form ionic bonds.
None-Metals:
Non-metals are usually good insulators of heat and electricity.
They are usually brittle and have dull appearence.
None-metals usually form covalent compounds.
1) Metals comprise 25% of the Earth's crust and are present in many aspects of modern life.
2) Many elements and compounds that are not normally classified as metals become metallic under high pressures.
1)In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks metallic attributes.
2) The nonmetals are divided into two categories reflecting their relative propensity to form chemical compounds namely reactive nonmetals and noble gases.
