Proton

The proton is one of the basic particles that make up an Atom. The proton is found in the Nucleus and has a positive electrical charge equal to the negative charge of an Electron. It has a mass similar to that of a Neutron. The number of protons in an atom defines the Atomic Number and hence the type of Element present.

Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution
