Answer:

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....
