example in class
so last week we did an example in class that said n=2; l=1; ml=-1
and the answer was that we had an electron that was in 2px state, I get the fact that it is 2p but why subscript x?

electrons ejected [ENDORSED]
If the energy of light is less than the ionization energy does that mean no electrons are ejected?

ionization energy
would the ionization energy be the same thing as work function?

electron mass
For tests will we have to know the electron mass?

how to express answer
in the answers to questions using the uncertainty equation, do you leave it with the greater than equal to sign or just an equal sign?

Re: Tests
Sometimes they will give it to you, but it is pretty easy and helpful just to memorize them.

Re: 1A.3
I believe the answer is C because E=hv and so frequency and energy are directly related.
