Question

Classify metal and non-metals on basis of their chemical property

Answer 1

✔ Classifying metal and non-metals on basis of their chemical property

Chemical properties of metal:-

• Reaction with oxygen

Metals reacts with oxygen to form metal oxide.

• Reaction with water

When metal react with water it forms metal hydroxide or oxide.

• Reaction with dilute acid

Metals reacts with diluted acid to form metals salt and hydrogen gas.

• Reaction of metal with salt of other metal

When metal reacts with salt sol. of other less reactive metal it displaces it from salt sol. and separate it out.

• Reaction with hydrogen

Generally metals do not combines with hydrogen but fer more reactive metal like sodium , potassium , calcium and magnesium combines with hydrogen and forms metal hydride.

Chemical properties of non metals:-

• Reaction with oxygen

Non metals reacts with oxygen to form non metallic oxide.

• Reaction of non metal with water

There is no reaction b/w non metals and water.

• Reaction with dilute acide

There is non reaction b/w non metals and dilute acide.

• Reaction of non metal with other non metallic salt

During this reaction a more reactive non metal displaces less reactive non metal from its salt sol.

• Reaction of non metal with chlorine

Non metals reacts with chlorine to form non metallic chloride.

• Reaction with hydrogen

Non metal reacts with hydrogen to form non metallic hydrogen.

$\mathcal{\huge{\fbox{\green{AnSwEr:-}}}}$

⚽ Chemical Properties of Metal :-

• Metals easily corrode very easily and fast.

• Metals lose electrons easily.

• Their outer shell has 1, 2 or 3 electrons.

• Most metals form metal oxides when they come in contact with the oxygen.

• Metals have low electro-negativities,they are electropositive elements.

• Metals are also good reducing agents.

⚾ Chemical Properties of Non-metal :-

• Non-metals generally have somewhere around 4 to 8 electrons inthe outer shell.

• Non-metals tend to gain or accept valence electrons.

• When they are exposed to oxygen,non-metals react with oxygen to form acidic oxides.

• Non-metals negativity; they are electro-negative elements.

• Non-metal elements are good oxidizing agents.

• These elements do not react with water.
