strong force & weak force
zeyta
gamma decay
That depends on the nuclear decay type. For gamma decay, the identity does NOT change, but for alpha and beta, it does.
Francium-223 decay to radium-223; each isotope have another type of decay.
That is the strong nuclear force.
Alpha decay. Alpha particles are the same as a helium-4 nucleus.
Alpha
an alpha particle
This type of decay is called β- (beta minus) decay. A link is provided to a related question with a descriptive answer that details the process.
Epsilon.
A. Epsilon
This is known as nuclear fission; the type of reaction that brings us nuclear power.
