Question

How many electrons would it take to equal the mass of a helium nucleus?

Answer 1

Answer:

Well, what is the mass of an helium nucleus.....?

Explanation:

Well the mass of 2 PROTONS, and 2 NEUTRONS is

6.64

. And clearly this mass relates to the

4

H

e

nucleus

And the electronic mass is

9.11
