Question

The mass of an electron is 9.1% 10-31kg and that of proton is 1.6x 10-27kg. Which of the two is heavier?

1)electron
2)proton​

Answer 1

Step-by-step explanation:

Proton because 10^-27 is greater than 10^-31.

Answer 2

Answer:

Electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

Step-by-step explanation:

A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleons". Wikipedia
