How many times larger are electrons compared to protons?

The mass of an electron is significantly smaller than that of a proton. In fact, an electron's mass is approximately 1/1836 of a proton's mass. This means that a proton is roughly 1836 times more massive than an electron.

When considering the choices, the correct understanding aligns with the concept that the mass ratio is not a multiple of the electron's mass being larger, but rather how many times larger the proton is in comparison to the electron. The value that accurately represents how many times larger a proton is compared to an electron is 1840, which is close to the commonly accepted value of 1836.

Thus, the correct answer reflects the fundamental understanding of particle mass in atomic structure, specifically that protons are substantially heavier than electrons.
