Boojho has learnt that non-metals on beating with a hammer are generally broken into pieces. Which of the following is a nonmetal?

• A. Iron nail
• B. Aluminium wire
• C. Copperplate
• D. Piece of coal

Answer 1

The correct option is D

Piece of coal

The explanation for the correct option:

(D) Piece of coal

• Iron, aluminium, and copper are all metals in the given options, but only carbon is a non-metal that may be broken with a hammer since non-metals are not malleable or ductile.
• Hammering causes coal, to break into bits.
• Coal is a fossil fuel with a dark colour that may be mined from the ground and used as fuel for a variety of things.
• Metals are malleable and ductile on the opposite. So, this is the correct option.

The explanation for the incorrect option:

(A) Iron nail

• Iron nail is a metal which is not non-metal. so this is an incorrect option.

(B) Aluminium wire

• Aluminium wire is a metal which is not non-metal. so this is an incorrect option.

(C) Copperplate

• Copperplate is a metal which is not non-metal. so this is an incorrect option.

Hence, the correct option is (D) Piece of coal is the non-metal.
