Question

Which of the following is not usually a property of metal?

• A. Conductivity
• B. Ductility
• C. Gas at room temperature
• D. Malleability

Answer 1

The correct option is C

Gas at room temperature

Explanation for the correct option:

Option (C) Gas at room temperature

1. Metals usually occur in the solid state at room temperature.
2. Also, The melting of the metals can not be reached at room temperature so they remain solid.
3. Metals are in solid-state due to the intermolecular forces between the atoms of metals being large.

Explanation for the incorrect option:

1. Option (A) Conductivity: It is the property of metals because metals have free electrons. Metals are good conductors of heat.
2. Option (B) Ductility: It is the ability to be drawn a material into wire without breaking down like- gold, silver, etc.
3. Option (D) Malleability: A material can be hammered into a thin sheet in this process.

Thus, we can say that gas at room temperature is not the property of the metal.

Hence, Option (C) is the correct answer.
