-This H-atom emission spectrum figure is derived from lots of experimental data and mathematical interpretation. The take home point is that electrons in an atom exist in particular energy levels/states. As stated, the quantum world follows a different set of laws than our macroscopic world we see all around us. I can make an analogy to a building...the quantum energy levels are kind of like the floors of a multi-story building like CSB...CSB has floors 1, 2, and 3. A person (or electron) can exist on any floor and at anytime we can count the number of people on any given floor...the key point to this is that every person is on "a" floor...1, 2, or 3 and these are the only options! sure you might find someone on the stairs going up or down, but the time spent on the stairs is minimal compared to being on a particular floor. The floors represent "levels or states." Note also that in order to go from one floor to another this requires energy...1st --> 2nd requires input of energy; 3rd --> 2nd releases energy, etc.

-Okay, so now that we know that electrons exist in well defined energy levels (or energy states...same thing), we need a way of keeping track of these levels. The values shown in the above figure, ''n = 2'', then 3, 4, 5, 6...and called the "principal" number...or '''''principal quantum number'''''.
