Question

Heavy hydrogen differs from normal hydrogen by virtue of

Answer 1

heavy hydrogen differs from normal hydrogen by virtue of mass no.

Answer 2

Answer: They differ by the virtue of the mass number.

Explanation:

Hydrogen is the first element of the periodic table. It has 3 isotopes, which are protium, deuterium and tritium. The formula for these three isotopes are $_1^1\textrm{H}\text{ , }_1^2\textrm{H}\text{ and }_1^3\textrm{H}$ respectively.

Deuterium and tritium are known as the heavy hydrogen and protium is known as the normal hydrogen.

The atomic number of these three isotopes are same but the mass number of these three isotopes are different.

So, they differ by the virtue of the mass number.
