Particles which can be added to the nucleus of an atom without changing its chemical properties are:

Correct answer: A. Neutrons

  • A. Neutrons
  • B. Electrons
  • C. Protons
  • D. Alpha particles

Explanation

When neutrons are added to the nucleus of an atom its chemical properties remain unchanged because the atomic number of particles remains the same. But when electron, proton, or alpha particles are added the atomic number changes which consequently, causes a change in chemical properties. The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.

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.
