7.3 Atomic And Nuclear Physics
Atomic and nuclear physics describes fundamental particles, their structure, properties and behavior. Atomic physics deals with the atom as a system consisting of a nucleus and electrons whereas nuclear physics studies atomic nuclei and their constituents and interactions. Take up the quiz below to gauge your knowledge in the field.

- A.
Energy from one fission reaction causes further fission reactions
- B.
nuclei produced in one fission reaction cause further fission reactions.
- C.
neutrons from one fission reaction cause further fission reactions.
- D.
Gamma radiation produced in one fission reaction causes further fission reactions
- 2.The source of the Sun’s energy is
- A.

- B.
A twelfth of the mass of one neutral atom of C12.
- C.
A sixth of the mass of one neutral atom of C12.
- D.
The mass of the nucleus of C12.
- 4.A neutron is captured by a nucleus. Which of the following gives the changes in the atomic (proton) number and mass (nucleon) number of the nucleus?
- A.
