An electron has a mass that is approximately ____________ that of the proton?
Correct answer: B. 1/1836 (approximately)
- A. 1836 (approximately)
- B. 1/1836 (approximately)
- C. 1
- D. ∞
Explanation
An electron is about 1836 times lighter than a proton, so its mass is approximately 1/1836 of the proton mass. The value 1836 describes the proton-to-electron mass ratio, not the electron-to-proton ratio.
