Question

The mass of an electron is negligible when compared to a proton.

• A. True
• B. False

Answer 1

The correct option is A

True

Atoms have electrons, protons, and neutrons as their fundamental particles. Mass of proton and electron is 1.673 $\times$ ${10}^{-27}$ kg and 9.11 $\times$${10}^{-31}$ kg respectively. Mass of a proton is 1836 times that of the electron. Hence, it is negligible when compared to protons.
