Verified step by step guidance1
Understand that the problem is asking for the relative electric charge of a proton in a simplified subatomic particle model.
Recall that subatomic particles include protons, neutrons, and electrons, each with characteristic charges: protons are positively charged, neutrons are neutral, and electrons are negatively charged.
Identify the standard convention for relative charge: the proton's charge is taken as +1, the electron's charge as -1, and the neutron's charge as 0.
Recognize that the relative charge is a dimensionless number representing the charge compared to the elementary charge (the charge of a proton).
Conclude that the relative charge of a proton is +1, meaning it has a positive charge equal in magnitude to the elementary charge.
