Which particle is a fundamental particle?
Correct answer: A. Electron
- A. Electron
- B. Hadron
- C. Neutron
- D. Proton
Explanation
•An electron is a kind of lepton which is considered a fundamental or elementary particle because they are not further divisible.•Hadrons are the heaviest particles; they are further composed of 2 quarks.•Protons and neutrons are baryons which are further composed of 3 quarks

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
