Write the names of isotopes of hydrogen . What is the mass of these isotopes ?

Explanation

To answer the question regarding the isotopes of hydrogen and their masses, we can follow these steps:

### Step 1: Define Isotopes
Isotopes are variants of a chemical element that have the same number of protons (same atomic number) but different numbers of neutrons. This results in different mass numbers for the isotopes.

### Step 2: Identify the Isotopes of Hydrogen
Hydrogen has three known isotopes:
1. **Protium (¹H)** - This is the most common isotope of hydrogen.
