Wavelength associated :

For A:

Energy change: E1-E2 = 0 - (-2) = 2 eV

So wavelength of the radiation emitted is:

(wavelength emitted is 256 nm, i.e, radiation B)

Maximum wavelength : emission A

Minimum wavelength: emission D

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?
