Electronic transitions for natrium atom

[rayman123]

Hi! I am writting my labbraport on electronspektrum for natrium atom.
Here is my electronic transitions but the teacher says that there are some transitions missing...have no clue which ones they might be...can someone explain to me what is he talking about? which are the missing electronical transitions which are not marked on my scheme?

my scheme:


thanks

Well, what rules did you use to determine which transitions are allowed and which ones aren't?

 

[rayman123]

$$\Delta l=+1,-1$$
$$\Delta S=0$$

OK, well, for starters, there are several states in your diagram which have no transitions at all. That implies that an electron in that state would be stuck there permanently - but hopefully that doesn't seem right to you. Start by looking at those.

For what it's worth, unless I miscounted (which is certainly a possibility), there are 29 transitions allowed by your rules that you haven't indicated in your diagram.

for sharing your lab report with us! It's great to see that you are studying the electron spectrum for the natrium atom. From your scheme, it looks like you have identified some of the electronic transitions, but there are actually many more that occur for this atom.

In general, electronic transitions occur when an electron moves from one energy level to another. In the case of natrium, which is also known as sodium, the electronic transitions can occur between the 3s, 3p, 4s, 4p, 5s, and 5p energy levels.

Some of the missing electronic transitions on your scheme may include:

- Transitions between the 3s and 4s energy levels
- Transitions between the 3p and 4p energy levels
- Transitions between the 4s and 5s energy levels
- Transitions between the 4p and 5p energy levels

There may also be transitions involving higher energy levels, but those are less likely to occur and may not be as significant for your lab report.

To identify the missing transitions, you can refer to the energy level diagram for natrium and look for possible jumps between energy levels. You can also consult with your teacher or do some additional research to confirm the missing transitions.

Overall, it's important to include all relevant electronic transitions in your lab report to accurately depict the electron spectrum for natrium and to ensure that your analysis is thorough and complete. Good luck with your report!
