The proton,the nucleus of the hydrogen atom,has a mass that exceeds that of the electron by approximately what factor?
A) 2000 times
B) 2 times
C) 100 times
D) 10⁴ times

Question

Quizplus · Accepted Answer

The mass of a proton is approximately 1.673 x 10^-27 kg, while the mass of an electron is approximately 9.109 x 10^-31 kg. Dividing the mass of a proton by the mass of an electron gives a ratio of approximately 1836. This means that the mass of a proton is approximately 1836 times greater than the mass of an electron, or roughly 2000 times greater. Therefore, choice A is the best answer.

The Proton,the Nucleus of the Hydrogen Atom,has a Mass That
