Unformatted text preview: which of the two semiconductors, n or p-type, do the electrons first flow into? Explain your choice. The different colours of light obtained from different LEDs relate to the size of the band gaps in the type of semiconductor that the electrons next flow into. 1. (c) Explain this statement (you may wish to make reference to the electromagnetic spectrum). Use an MO band diagram to illustrate your answer. 2. (a) In the boxes below give the The MO energy diagram for the diatomic molecule Mg 2 The MO energy bands for Mg metal 2. (b) The diatomic molecule Mg 2 does not exist but Mg metal does, using the diagrams you gave above explain why this is so....
