In an ion with an unknown charge, the total mass of all the electrons was determined to be 1.640 x [tex]10^{-26}[/tex] g, the total mass of its protons was 4.015 x [tex]10^{-23}[/tex] g, and the total mass of its neutrons was 4.690 x [tex]10^{-23}[/tex] g. What is the identity, charge, and mass number of this ion? Electron one mass = 9.109 x [tex]10^{-31}[/tex] Proton one mass = 1.673 x [tex]10^{-27}[/tex] Neutron one mass = 1.675 x [tex]10^{-27}[/tex]
