An ion beam pulse contains 40 identical ions. Each ion is formed only by removing outer electrons from a neutral atom represented by 2351V{}^{51}_{23}\mathrm{V}2351V.
The total relative charge of the ions in the pulse is +120.
Calculate the total number of neutrons and the total number of electrons in the pulse.
