My question is simple, yet a thorough search of Google brought me no closer to finding the answer. I found countless articles explaining what the emission spectra of an element was, but none which satisfactorily told me why they contained more than one line.

I understand the core concept. That is, if you add energy to an atom, which may be the heat from the Bunsen flame, the atoms will gain that energy and their electrons may be promoted to a higher energy level. Since this energy level is unstable the excited electrons return to their stable state, emitting energy as visible light, the frequency of which directly relates to difference between energy levels.

My question is do all the electrons jump when energy is applied to them? Do only a selected few jump? Are the jumps for a particular element consistent? What precisely produces the unique spectra for each element? Why, my brain moans to find the answer!

Smart answers please, I also thank you in advance.

I have read the online journal for this one, and watched the episode, but no answer for it. If anyone knows, I would love to know the answer to this question. I need to know the answer for a Josh Bernstein group for a group for a prize.

Someone stated to me that spearmint is used to relieve heart burn. I was wonder if this is because it's an acid or a base?

I need to know this answer for a Josh Berstein group to win a prize, and I don't know where to look for it online.
I can't find this answer on the online journal for Digging For The Truth, and I'm really desperate to know the answer. I think if I try to look it online in the search engines, I'd be way too confused. If there's any help, thanks, because I think that this is one of the second season episodes that I can't watch to get the anwer for. The online journal doesn't help me because I've read it so many times, that I can't see the name of the guy or what his job was on Magellan's ship in the 1520s.
