What are the 3 points of Strong Nuclear Force.

- If the range is between 3-4 femtometres
- It has the same effect between two protons as it does between two neutrons or a proton and a neutron.
- It is an attractive force 3-4fm as separations than this, a repulsive force acts to prevent neutrons and pr

What is alpha radiation?

Consists of alpha particles, which has two protons and two neutrons which an unstable nucleus, it emits an alpha particle decreases its atomic by 2 and nucleon by 4.

What is Beta radiation?

Consist of fast moving electron, its beta particle has only an electron

What is the difference between a Beta minus and a Beta plus particle?

A Beta plus particle has a positron and a neutrino, while a Beta minus particle has a electron and a antineutrino.
