Hi guys,
I'm researching excited electrons in metals at the moment.
I have a question which has probably being asked somewhere before but I can't find it using the search.
I understand that the Pauli excl. princ. staes that you can't have two electrons with the same quantum numbers in the same atom. I understand this falls out of the maths somewhere but is there an intuitive reason for this?
My second question is about energy bands in solids;
when atoms combine in a solid, they basically act as one big atom, so there has to be lots of states available to the electrons, hence energy bands, right? But if this is so, and the amount of energy levels is dependant on the number of atoms, if you have a huge piece of metal, will you have loads of high energy bands, perhaps high enough to escape the metal itself?
Thanks as always
