Hydrogen bomb is based on the principle of :
- artificial radioactivity
- nuclear fusion
- natural radioactivity
- nuclear fission
The Correct Option is B
Solution and Explanation
Hydrogen bombs are based on the principle of uncontrollable nuclear fusion. In Nuclear fusion, the nuclei of two light atoms combine to form a new nucleus.
Thus, the correct answer is B Nuclear Fusion.
Applications of Nuclear Fusion
- No combustion occurs in nuclear power (fission or fusion), so there is no air pollution.
- Fusion reactors will not produce high-level nuclear wastes like their fission counterparts, so disposal will be less of a problem.
- Wastes will not be of weapons-grade nuclear materials as is the case in fission reactors.
Additional Understanding: Difference Between Nuclear Fission and Nuclear Fusion
| Nuclear Fission | Nuclear Fusion |
|---|---|
| Nuclear fission splits a heavy atom into two or smaller ones. | Nuclear fusion combines two or more small atoms to form a large atom. |
| Nuclear Fission doesn't occur naturally. | Every star uses nuclear fusion to produce energy. |
| It produces a large quantity of energy. | It produces greater energy than the fission reaction. |
Top Questions on Nuclear physics
- ${ }_{92}^{238} U$ is known to undergo radioactive decay to form ${ }_{82}^{206} Pb$ by emitting alpha and beta particles. A rock initially contained $68 \times 10^{-6} g$ of ${ }_{92}{ }^{238} U$. If the number of alpha particles that itwould emit during its radioactive decay of ${ }_{92}^{238} U$ to ${ }_{82}{ }^{206} Pb$ in three half-lives is $Z \times 10^{18}$, then what is the value of $Z$ ?

Concepts Used:
Nuclear Physics
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons
Radius of Nucleus
‘R’ represents the radius of the nucleus. R = RoA1/3
Where,
- Ro is the proportionality constant
- A is the mass number of the element
Total Number of Protons and Neutrons in a Nucleus
The mass number (A), also known as the nucleon number, is the total number of neutrons and protons in a nucleus.
A = Z + N
Where, N is the neutron number, A is the mass number, Z is the proton number
Mass Defect
Mass defect is the difference between the sum of masses of the nucleons (neutrons + protons) constituting a nucleus and the rest mass of the nucleus and is given as:
Δm = Zmp + (A - Z) mn - M
Where Z = atomic number, A = mass number, mp = mass of 1 proton, mn = mass of 1 neutron and M = mass of nucleus.
