Question

Hydrogen has three isotopes 1H, 2H, and 3H. What is the difference between these three isotopes?

Answer 1

Hydrogen has three isotopes namely ¹H₁, ²H₁, ³H₁

The difference between them are they are having same atomic number but different atomic mass due to difference in number of neutrons

¹H₁ --- has no neutrons

²H₁-- has 1 neutron

³H₁ -- has 2 neutrons

As the atomic number is same, chemical properties of Isotopes are same only physical properties they differ in.

Among The three isotopes of Hydrogen only ³H₁ is radioactive.

Answer 2

The word isotopes are referred to the nucleus and with the same Z size.

This initially brings it by 1H, 2H, and so on.

The Hydrogen elements are taking place by evaluating the one single proton and denotes z=1.

It differs in the number of their neutrons and no neutron, deuterium has one and tritium has two neutrons.
