Answer 1

metals: Metals are used to mean those natural elements which are solid, lustrous, opaque and higher in density. Metals have a very high boiling and melting point. They effectively conduct heat and electricity. In metals, the atoms are arranged in the crystal structure. They act as reducing agents, as they lose valence electrons and form cations. Some examples of metals are silver, aluminium, gold, lead, nickel, copper, titanium, magnesium, iron, cobalt, zinc, etc. Metals are hard and are commonly used in making machinery, water boilers, agriculture equipment, automobiles, industrial equipment, utensils, aeroplanes, etc.

non metals: Non-metals, as the name suggest, is the natural element, which lacks metallic properties. These are usually present in the solid or gaseous state, except Bromine, the only non-metal that exist in liquid form. They are soft, non-lustrous (except iodine) and good insulators of heat and electricity.  E.g. Nitrogen, oxygen, hydrogen, argon, xenon, chlorine and so forth.

Answer 2

Answer:

METALS

•Are malleable, i.e., can be made into sheets

•Are sonorous

•Good conductors of heat and electricity

•Are ductile, i.e., they can be made into wires

NON-METALS

•Non-malleable

•Not sonorous

•Poor conductors of heat and electricity

•Aren't ductile

hope this helps
