Protons, Neutrons and electrons

Protons has the relative mass of 1 and the Charge of 0

Neutrons has the relative mass of 1 and the charge of +1

however electrons has the relative mass of 1/1840 and the charge of -1

* when talking about the charge make sure you mention the negative and positive.

* the relative mass of electrons differ ... some teachers say it's 1/2000 ?
