Homework Help: Net Charge removing electrons

  1. Jun 13, 2005 #1
    1.16 g nugget of pure gold has a net charge of 0. What would be its net charge after it has 1% of its electrons removed???

    I'm assuming you may have to convert it to moles use avogadros number, use the electrical charge of 1.602E -19 and mulitply the answer by .01 but i can't get an answer

    How many electrons does that many moles have. How many electrons is 1%? Whats the charge of that 1%?

    The atomic number of gold is 79, which means each atom has 79 electrons.

    Now the problem states 1% of electrons, not 1% of valence electrons, which is a smaller population.
