Answer:
B
Explanation:
Protons of atoms are the atomic particles with a positive charge while electrons bear a negative charge. Protons are found in the nucleus together with neutrons (that have no charge).

The electrons orbit around the nucleus and are kept in orbit by the electromagnetic attraction of the positive nucleus.
