Nuclear Fusion

Nuclear fusion is a type of nuclear reaction. In nuclear fusion, two or more than two lighter atomic nuclei combine to form a heavier nucleus. During this process, an enormous amount of energy is released. This energy is called nuclear energy. Nuclear fusion is the energy source of the sun and stars.

Fusion Bomb

A fusion bomb is also known as a thermonuclear bomb or hydrogen bomb which releases a large amount of explosive energy during a nuclear chain reaction when the lighter nuclei in it, combine to form heavier nuclei, and a large amount of radiation is released. It is an uncontrolled, self-sustaining nuclear chain reaction where isotopes of hydrogen combine under very high temperature to form helium. They work on the principle of operation of atomic fusion. The isotopes of Hydrogen are deuterium and tritium, where they combine their masses and have greater mass than the product nuclei, get heated at high temperatures, and releases energy.

Question

## Characteristics of Alpha Decay

When studying alpha decay, several key characteristics can help identify and differentiate this type of radioactive decay from others. Select each of the following statements that is a characteristic of alpha decay:

- ☐ The **mass number** of the nucleus that decays **decreases by 4**.
- ☐ The radiation that is produced carries a **negative charge**.
- ☐ The **atomic number** of the nucleus that decays **increases**.
- ☐ The **chemical element** of the nucleus that decays **remains unchanged**.
- ☐ The **mass number** of the nucleus that decays **remains unchanged**.
- ☐ The **mass number** of the nucleus that decays **decreases by 2**.
- ☐ The radiation that is produced carries a **positive charge**.
- ☐ The **atomic number** of the nucleus that decays **decreases**.

Explore each option to understand which changes occur specifically during alpha decay. This understanding is essential for accurately describing and predicting the behavior of radioactive materials.
