- Nuclear structure
- Protons
- Neutrons
- Atomic number = no. of protons
- Mass number = no. of protons & electrons
- Isotopes
- Atoms of the same
atomic number but
different mass number
- Radioactivity
- nucleus of an unstable atom loses
energy by emitting particles of
ionizing radiation
- Radiation
- Emission of particles of matter or
photons of energy
- Types
- Alpha
- Beta
- Gamma
