Neutron is a fundamental particle which have–
There are four options given to choose from regarding the charge and mass of a neutron. Let's analyze each option to determine the correct answer.
Option A: 1 unit charge and 1 unit mass
- A neutron has no charge, so this option is incorrect.
Option B: No charge and 1 unit mass
- This option correctly states that a neutron has no charge. Neutrons are electrically neutral particles.
- Neutrons do have mass, with a mass of approximately 1 atomic mass unit (u) or 1.67 × 10^-27 kg.
- Therefore, option B is correct.
Option C: Have no charge and mass
- This option is incorrect as it implies that a neutron has no mass. However, neutrons do have mass.
Option D: Have –1 unit charge and 1 unit mass
- This option is incorrect as it states that a neutron has a negative charge. Neutrons are electrically neutral and do not possess any charge.
Therefore, the correct answer is option B: Neutrons have no charge and 1 unit mass.

Understanding Neutrons
Neutrons are one of the three primary components of atoms, alongside protons and electrons. Let's explore their characteristics in detail.
Charge Characteristics
- Neutrons have no electric charge, making them electrically neutral.
- This neutrality is crucial for stabilizing the nucleus of an atom, as it helps balance the positive charge of protons.
Mass Properties
- Neutrons have a mass approximately equal to 1 atomic mass unit (amu).
- While their mass is very similar to that of protons, electrons have a negligible mass in comparison.
Role in Atomic Structure
- Neutrons play a key role in the stability of atomic nuclei.
- The presence of neutrons helps mitigate the repulsive forces between positively charged protons.
Implications of Neutrons
- The number of neutrons in an atom can vary, leading to the formation of isotopes.
- Isotopes have the same number of protons but different numbers of neutrons, affecting their nuclear stability and properties.
Conclusion
In summary, the correct answer to the question regarding neutrons is option 'B': they have no charge and 1 unit mass. This unique combination of properties is vital for the structure and behavior of matter in the universe. Understanding neutrons is essential for fields such as nuclear physics, chemistry, and various applications in technology and medicine.
