Question

List any five properties of metals and non-metals

Answer 1

Metal : A substance that has a tendency to lose electrons and form cation is considered as metal. they have the following properties

• High melting point
• Good conductors of heat & electricity
• High tensile strength
• malleable & ductile
• Lustrous and sonorous in nature

For Example – Iron [ Fe], Cobalt [Co],Nickle [Ni], etc.

Non-metal: A substance that has a tendency to lose electrons and form anion is considered as metal. they have the following properties

• Non-metals are non-lustrous except for iodine
• Non-metal may be solid, liquid, or gases at room temperature
• They are brittle in nature
• They are neither tough nor strong
• Non-metals are bad conductors of heat and electricity except graphite

For Example – oxygen[O₂ ], Nitrogen [N₂ ], chlorine [ Cl₂]
