Explanation:
The electrical charge on protons are positive charges.
Protons are subatomic particles and they carry positive charges on them. In all instances, they are found in the tiny nucleus along with neutrons.
Both protons and neutrons contributes the bulk mass of an atom whereas electrons is negligible and inconsequential to the mass of the atom.
- Electrons carry negative charges within an atom with a charge of -1
- Neutrons are uncharged subatomic particles.
- Protons carry positive charges, +1
