Electrons are lost from outside of the nucleus

An atom consists of three particles

  • The proton, +1
  • The neutron, no charge
  • The electron, -1

Now the proton and neutron compose the nucleus which lies inside and at the center of the atom, while the electron occupy the orbit or shell outside the nucleus.

The atomic number is equal to the proton number.

The proton and neutron number gives the mass number.

An atom will loose or gain electrons outside the nucleus , but in the  outermost shell with partly filled with electrons.
