What is the relative charge of a proton?

Explanation:
Charge comes in discrete units called the elementary charge. A proton has one unit of positive charge, so its relative charge is +1. In contrast, an electron has one unit of negative charge (-1) and a neutron has no charge (0). The proton isn’t +2 because a single proton carries only one positive unit of charge.
