Study Notes
Atomic Nucleus
- The nucleus of an atom is composed of two main subatomic particles: protons and neutrons.
- Protons are positively charged and have a mass of approximately 1 atomic mass unit (amu).
- Neutrons have no charge and a mass of approximately 1 amu.
Role of Neutrons
- Neutrons play a crucial role in the nucleus of an atom, helping to stabilize the atom by counteracting the positive charge of protons.
- The number of neutrons in an atom can vary, leading to different isotopes of the same element.
- Neutrons also participate in nuclear reactions, such as nuclear fission and fusion.
