Question

The mass of how many electrons would be the closest of the mass of one proton plus one neutron?

A. 1

B. 2

C. 1836

D. 3672

Answer 1

Strange as it may seem, it takes 1836 electrons to make the mass of ONE proton or neutron.

So if you have one proton AND one neutron in a jar, there's enough mass in there to make 3672 electrons.

That's choice-D .
