1. The problem statement, all variables and given/known data

a hydrogen nucleus and a nucleus of an unknown atom are stationary, 5.0x10^-10m apart, the electric charge on the hydrogen nucleus is 1.6x10^-19C.

express the charge you have calculated for the unknown nucleus as a whole number multiple of the charge on the hydrogen nucleus, you may assume this number is the atomic number of the unknown nucleus, ie the number of protons

2. Relevant equations

I used Fe= -ke Q1 Q2 / r^2

3. The attempt at a solution

my calculation gave me the charge on the unknown nucleus to be -2.39x10^-19C

however, when i try to turn this into some whole number compared to 1.6x10^-19, i either get 1.5 or 0.6, neither of which are whole numbers.

please help with this part of the question, even if its just a nudge as to what on earth is actually being asked.....

neither integers nor any similar work appears in my coursebook and my tutor isnt returning my emails.

please help
