Question

1) In a photoelectric effect experiment, a studentshines a light of greater than the threshold frequency upon thesurface of the metal. She observes that after a long time,the number of ejected electrons begins to decline. Can youexplain why? 2) Look up the electron configuration of Rhodium. Why is itexceptional? Explain. 3) Draw the orbital diagram for copper. 4) How many lobes will the f orbitals have? Explain. 1) In a photoelectric effect experiment, a studentshines a light of greater than the threshold frequency upon thesurface of the metal.

Explanation / Answer

   1) when the time was passed after the lightsource used to ejected for electrons from the surface of the matel, gradully     thr frequency of light source falls downhence the emitted electrons were declined as long as timepassed. 2) generally the transition metals exhibit differentoxidation states.due to the crystallographic structure and thermal, conductivity properties the electronic configuration ofRhodium adopted 4d8 5s1 instead of 4d7 5s2.
