Question

Electrons carry a ___ charge and protons carry a ___ charge.

• A. positive, positive
• B. positive, negative
• C. negative, negative
• D. negative, positive

Answer 1

The correct option is D

negative, positive

Protons carry a positive charge. Hence, the charge of each proton will be $+1.6\times {10}^{-19}C$

Electrons carry a negative charge. Hence, the charge of each electron will be $-1.6\times {10}^{-19}C$

By convention, we take the charge on an electron to be negative and the charge on a proton to be positive.
