### Question 1B.7

The question is about different aspects of sodium, but in the solutions guide it seems to have the energy per atom of sodium as a given. Will we be provided with such information on tests?

I'm not completely sure but I think that the energy per atom can be found at the back of the textbook for the referencing during homework and should be given for a test.

I'm pretty sure that we would have to work that information out ourselves because the Einstein equation tells us how many Joules are emitted per atom (remember the 1 atom emitting an electron to 1 photon ratio).
