A. Alpha particle
B. Neutron
C. Electron
D. Proton
E. All of these

Neutrons are the electrically neutral particles present in the nucleus of an atom.

A neutron is a neutral particle.

Unlike protons (positive charge) and electrons (negative charge), neutrons have no electric charge, making them neutral particles.
Key points about neutrons:

  • Found in the nucleus of an atom
  • Approximately the same mass as a proton
  • Considered a stable particle only within the nucleus of an atom

The correct answer to the question: "Which of the following is a neutral particle ?" is "Neutron".
