Question

A neutron has
A. positive charge
B. negative charge
C. no charge
D. all of the above

Answer 1

Hint: Neutrons are the subatomic particles present in the nucleus of an atom. The neutron does not resemble a positively charged proton or negatively charged electron. Unlike protons and electrons which lose energy in small quantities, neutrons rarely collide with atoms and completely lose their energy.

Complete step by step answer:
The neutron is one of the two entities of the nucleus out of which one is the proton. The attractive force which holds the nucleus of the atom together affects both the constituent proton and neutron.
The neutrons show stability inside the nucleus. When the neutron starts moving freely, the stability is lost and the neutron becomes an independent state.
Neutrons are the uncharged particles present in the nucleus of an atom and due to its neutral nature, they do not take part in electromagnetic interaction and do not form ionization of atoms.
As neutrons do not possess an electric charge, they can freely penetrate the electronic shell of the atom and do not repel by the force (Coulomb field) of the nucleus. Therefore, the neutron is used to study the nucleus, biological structure and is resourceful for agriculture, medicine, and science.
Thus, the neutron has no charge.

Therefore, the correct option is C

Note:
The mass of a neutron is more than a proton. Due to this reason Einstein gave a famous mass-energy relation which gives the equation of this extra mass with the extra energy. Thus, this energy neutron can be converted to the proton by releasing an electron and an antineutrino.
