Hydrogen has three isotopes: protium (1H), deuterium (2H or D) and tritium (3H or T). They have nearly same chemical properties but different physical properties. They differ in
- Number of protons
- Atomic number
- Electronic configuration
- Atomic mass
The Correct Option is D
Solution and Explanation
The correct answer is (D) : Atomic mass
1H, 2D and 3H have same atomic number but their atomic masses are different. Isotopes have same atomic number i.e. same number of protons.

Hydrogen
Hydrogen is the most abundant element in the universe, constituting approximately 75% of its elemental mass. It is a colorless, odorless, and tasteless gas that exists in a diatomic form (H2) at standard conditions. Hydrogen has the atomic number 1, which means it has only one proton in its nucleus, making it the simplest and lightest element.
Hydrogen has a wide range of applications, including fuel for transportation, power generation, and heating. It can be produced from various sources, such as fossil fuels, biomass, and water. The most common methods of producing hydrogen are steam methane reforming and electrolysis.
In addition to its use as a fuel, hydrogen is also used in the chemical industry to produce ammonia, methanol, and other chemicals. It is also used in the production of electronics, such as microchips, flat-screen displays, and semiconductors.

Hydrogen has unique properties that make it a promising energy carrier for a sustainable future. When burned in air or used in a fuel cell, it produces only water, making it a clean and renewable energy source. However, the high cost of producing and storing hydrogen, as well as the lack of infrastructure, remain significant challenges to its widespread adoption. Nonetheless, ongoing research and development efforts aim to overcome these challenges and harness the potential of hydrogen as a key element in a low-carbon energy system.
