Answer 2

Mass of electron: 9.1093897x10^-31 Kg

Mass of neutron: 1.6749286x10^-27 Kg

Mass of proton: 1.6726231x10^-27 Kg

Theoretical mass of helium nucleus: 2 x 1.6749286x10^-27 Kg+2 x 1.6726231x10^-27 Kg=6.6951x10^-27 Kg

9.1093897x10^-31 Kg x e-=6.6951x10^-27 Kg

e-=6.6951x10^-27 Kg/9.1093897x10^-31 Kg

=7350 electrons

Answer 3

Two protons, two neutrons, two electrons, one shell.
