* Protons: The nucleus of an atom contains protons, which have a positive electrical charge.
* Neutrons: The nucleus also contains neutrons, which have no charge (they are neutral).
* Overall Charge: Since protons are positively charged and neutrons are neutral, the overall charge of the nucleus is positive.
The positive charge of the nucleus is balanced by the negative charge of the electrons orbiting around it, giving the atom a neutral charge overall.
