Question

3.Mass of electron is​

Answer 1

Answer:

9.10938356 × 10 ^ -31 kilograms

Answer 2

Explanation:

The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton. An electron is therefore considered nearly massless in comparison with a protonor a neutron, and the electron mass is not included in calculating the mass number of an atom.
