Question

what are two chemical properties of metals and non metals?​

Answer 1

Answer:

Chemical Properties of Metals

• The density of metals is usually high.

Metals are malleable and ductile.

Metals form an alloy with other metals or non – metals.

Some metals react with air and corrode. For e.g. Iron.

Metals are good conductors of heat and electricity. Lead is an exception.

Generally, metals are in a solid state at room temperature. Except for Mercury. Mercury is in a liquid state.

Many metals produce metal oxide by burning in the oxygen of the air. Highly reactive metals react violently when they’re burnt in oxygen.

Answer 2

Chemical properties of Metals:-

1) Rection with oxygen:- They react with oxygen to form basic oxide.

Metal+Oxygen---->Metal oxide

2)Rection with acids:- Strong metals like sodium, calcium and magnesium react with acids to displace hydrogen and release hydrogen gas. But some less reactive metals like copper do not react.

eg: Zinc+ Hydrochloric acid-----> Zinc chloride+H2

Copper+Hydrochloric acid----> no reaction

Chemical properties of non-metals:-

1) Reacrion with oxygen:- They react with oxygen to form acidic oxide.

eg:- Carbon+Oxygen----> Carbon dioxide

2) Reaction with acid:- Non-metals do not react with acids becoause they can not give their electrons. They only for covalent bond

Non-metal+acid---> no reaction
