An electron is in a region outside the nucleus. An electron a) Is larger than a proton and has no charge
b) Has less mass than a proton and has a negative charge
c) Is smaller than a proton and has no charge
d) Has a positive charge

b

Explanation:

electrons lie in the orbits of the atom. they are negatively charged and they are very small in size. they have very less mass than proton. ele tron has 1/1840 mass of proton.

the correct answer would be d. hope this !

it is stable as it is in group 0 which have full outer shells of electrons
