Electric exist at a distance from two charged spheres.

The answer to this question is "FIELD".
Electric "field" exists at a distance from two charged spheres. What happens is, we have two spheres either one is positively charging while the other one is negatively charged. When these spheres are placed in the same region, one sphere will tend to pull the negatively charged sphere and the two attracts each other. It is developing an electric field.

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.
