Atomic Structure
... The nucleus (the positively-charged center of the atom) is held together by a strong nuclear force, which “glues” protons together. The electrons are attracted to the nucleus by an electromagnetic force. This holds the atom together. Gravity plays a part, too, but is the weakest of the forces in nat ...
