I'm sure im missing something simple here but... Suppose a 1.72 g nugget of pure gold has zero net charge. What would be its net charge after it has 1% of its electrons removed? So i know that an electron is 9.109 x 10^-31 kg, and has a charge of -1.602 x 10^-19C. However, how do i know the split of electrons and protons in the gold bar? I'd assume im trying to get to mass of electrons / mass of electron, that times the charge of an electron divided by 100???
