Question

NEED HELP FAST. If anybody is great with Geometry or Physical Science, PM me.

The mass of an electron is......

A) equal to the mass of the proton and the neutron

B) not significant to the overall mass of the atom

C) higher than the mass of the proton or the neutron

Answer 1

Answer:

B

Explanation:

I say it's B because I eliminated answers. A is wrong because the mass of an electron is 5.489×10−4 and the mass of a proton and neutron is 1.674929 x 10-27 kg. It's not C because the mass of a proton and neutron is greater than an electrons. Therefore it's B is greater
