Question

The mass of the electrons is negligible when compared to the mass of protons.

• A. True
• B. False

Answer 1

The correct option is A

True

Atoms have electrons, protons and neutrons as the fundamental particles. Electrons are negligible in mass ($9.10938356\times {10}^{-31}kg$) when compared to protons and neutrons. Mass of proton is $1.6726219\times {10}^{-27}kg$, which is approximately 1837 times that of the electron.
