The work function of an element is the energy required to remove an electron from the surface of the solid. the work function for rhodium is 480.5 kj/mol (that is, it takes 480.5 kj of energy to remove 1 mole of electrons from 1 mole of rh atoms on the surface of rh metal). what is the maximum wavelength of light that can remove an electron from an atom in rhodium metal?

What are the charges of the subatomic particles by choosing the answer from the drop down menu. protons have a (+1,0,or-1). (protons, neutrons, electrons) have a 0 charge. 3.) electrons have a (+1,0,-1)

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
