Neutron

Definition

A neutron is a subatomic particle found in the nucleus of an atom that has no electric charge. It plays a crucial role in the stability of atomic nuclei and interacts with other particles through the strong nuclear force.

5 Must Know Facts For Your Next Test

1. Neutrons have no electric charge, making them electrically neutral.
2. Despite having no charge, neutrons contribute to the mass of an atom and play a key role in nuclear reactions.
3. Neutrons interact with charged particles through indirect means such as the nuclear force but do not participate directly in electromagnetic interactions.
4. The number of neutrons in an atom can vary, leading to different isotopes of the same element.
5. Neutrons can influence electric fields indirectly by altering the distribution of protons within an atomic nucleus.
