I will tell you the "how", as for the "why", it would take considerable wits and a lifetime of study into string theory to figure out, and unfortunately I posess neither.

In one word they are attracted by the ELECTRIC force between them.

The proton has a positive charge (=+1.6 x10^-19 C) and
the electron has a negative charge (=-1.6 x 10^-19 C).
Please note that the proton has a positive charge and electron a negative charge.


Charles-Augustin de Coulomb has shown in 1785 that electrical particles with opposite charges attract one another and conversely, charges with the same sign repel one another. The magnitude of the attractive force (or repulsive force) is given by the formula

F = kc * q1 * q2 / r^2 where

kc is a constant called the electrostatic constant = 8.988×10^9 N m^2/C^2
q1 is the magnitude of charge #1 in C (Coulomb)
q2 is the magnitude of charge #2 in C
r is the distance between both particles in m (meter)

This force is called the ELECTRIC force.

The proton has a positive electrical charge and the electron has a negative electrical charge.

None at all, it's not about reason. That would assume some purpose or goal behind the universe and there isn't any of either.

proton has a positive chare and electron has a negative carge so coulombian interaction F = -qq'/r^2
