What is a stable isotope?
A stable isotope has a nucleus that does not disintegrate
1 of 7
What is the strong nuclear force?
The strong nuclear force is the force that holds the stable nuclei together. It overcomes the electrostatic force of repulsion between the protons in the nucleus.
2 of 7
What is the range of the strong nuclear force?
Its range is no more than about 3-4 fentometres
3 of 7
What are the three types of radioactive decay?
Alpha decay, Beta Decay, and Gamma Decay
4 of 7
What happens in alpha decay?
An alpha particle (made of two neutrons and two protons) is emitted from the unstable nucleus
5 of 7
What happens in beta decay?
An electron and an antineutrino are emitted from the nucleus
6 of 7
What happens in gamma radiation?
Gamma rays are emitted from the unstable nucleus, after an alpha or beta emission.
