Mass: Neutrons have a mass of approximately 1.675 x 10^-27 kilograms, which is similar to the mass of a proton.
Charge: Neutrons have no electric charge, making them electrically neutral.
Stability: Neutrons are relatively stable when they are within an atomic nucleus, but they can become unstable when outside the nucleus and undergo decay processes.
Importance of Neutrons:
Neutrons play a crucial role in determining the stability and properties of an atom. Some key points to consider are:
Nuclear Stability: Neutrons contribute to the stability of the atomic nucleus. The number of neutrons in relation to protons can affect the stability of an atom.
Neutron Activation: Neutrons can induce radioactivity in certain materials through a process called neutron activation. This property is utilized in various scientific and industrial applications.
