Question

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

Answer 1

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

Explanation:

Well the mass of 2 PROTONS, and 2 NEUTRONS is `6.64xx10^-27 *kg`. And clearly this mass relates to the `""^4He` nucleus

And the electronic mass is `9.11×10^(−31)* kg`

And so we divide the former by the latter...

`=(6.64xx10^-27 *kg)/(9.11×10^(−31)*kg)=??`

I make it about 10000 electrons....
