Question

Which of the following atomic and physical properties of hydrogen is false?

• A. Hydrogen > Deuterium > Tritium; (melting point/ K)
• B. Hydrogen < Deuterium < Tritium; (boiling point/ K)
• C. Hydrogen < Deuterium < Tritium; (density/gL${}^{-1}$)
• D. Hydrogen > Deuterium > Tritium; (% relative abundance)

Answer 1

The correct option is A Hydrogen > Deuterium > Tritium; (melting point/ K)

The atomic and physical properties of hydrogen represented by option $A$ is false.

The true properties are Hydrogen < Deuterium < Tritium ; (melting point/ K).

With an increase in the mass, the melting point increases.

Hence, option $A$ is the answer.
