- What is Radioactivity?
- Ionisation- addition or removal of atoms
- Atomic number
- Number of protons
- Proton- nucleus- positive charge- mass of one
- Number of protons
- Atomic mass
- Protons and neutrons in the nucleus
- Neutron- nucleus- neutral- mass of one
- Protons and neutrons in the nucleus
- Electron- shell- negative charge- no mass
- Electrostatic force tries to push the nucleus apart
- More protons will increase electrostatic force
- Greater than the nuclear force
- Nucleus decays
- Greater than the nuclear force
- Large diameter weakens strong force effect
- Over a short distance
- Small nucleus balances this
- More protons will increase electrostatic force
