Hi Shubhi,

The de-Broglie wavelength associated with moving electron is 

begin mathsize 14px style straight lambda equals straight h over mv equals fraction numerator straight h over denominator straight m square root of begin display style fraction numerator 2 eV over denominator straight m end fraction end style end root end fraction equals fraction numerator straight h over denominator square root of 2 meV end root end fraction end style

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
