Name the four fundamental forces of nature, the forces from which all others are derived

Gravitational Force - weak, long ranged (can act over very long distances) and always attractive. Electromagnetic Force - weak but long ranged. It can be either be attractive or repulsive. Strong Interaction - very strong, short ranged, attractive but can also be repulsive, holds nuclei together. Weak Force - weak and short ranged. It is the force responsible for radioactive decay.

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
