Can You Determine the Charge to Mass Ratio from Nucleon and Proton Numbers?

[nikelberry]

hi,
im have a few trouble working out this question,

Calculate the ratio of charge/mass in Ckg^-1
for the nucleus stated below

236
U
92

now i know the formula to use BUT I am having trouble with calculating the figures for Charge and Mass.
(i know that the charge is 1.6x10^-19 )

Please tell us the formula that you know you should use. Also, do you know the meaning of the numbers 236 and 92?

the formula is - specific charge = charge / mass

and the 236 is the nulceon number & 92 is the proton number

Can you calculate the charge and mass from the nucleon number and proton number?
