Question

Choose the option which is not a property of metal-

• A. Metal is a good conductor of heat
• B. Except for mercury all the other metals are in liquid state
• C. Metals form cations in aqueous solution
• D. The oxides of metals are basic in nature

Answer 1

The correct option is B

Except for mercury all the other metals are in liquid state

Explanation for Correct answer:-

Option (b) Except for mercury all the other metals are in liquid state

• Mercury exists in liquid state and generally, metals are in solid-state.
• So, it is not right for metals.
• Hence it is the correct option.

Explanation for incorrect answer:

option(a) Metal is a good conductor of heat:

• Metals are good conductors of electricity.
• Hence it is the incorrect option.

option(c) Metals form cations in aqueous solution

• Metals have the tendency to form cations in an aqueous solution.
• Hence it is the incorrect option.

option (d) The oxides of metals are basic in nature

• The oxides formed by metals are basic in nature.
• Hence it is the incorrect option.

Therefore, option(b) Except for mercury all the other metals are in liquid state is the correct answer.
