Answer:

Step-by-step explanation:
Electrons and protons are both subatomic particles in an atom.
First, analyze both.
Electron
- Location: Surrounding the nucleus
- Mass: 1/1840 amu
- Charge: Negative and -1
Proton
- Location: In the nucleus
- Mass: 1 amu
- Charge: Positive and +1
So, we see that the electron has a charge of -1 and the proton has a charge of +1. The correct answer must be choice D.
