Why Should n Be 1 When Calculating I3 for Lithium Using the Rydberg Formula?

Click For Summary
SUMMARY

The discussion centers on the calculation of the ionization energy (I3) for lithium (Li) using the Rydberg formula, specifically the equation Z²hR/n². The correct value for n in this context is established as 1, contrary to the initial assumption of n=3. This clarification is essential for accurate calculations of ionization energies in atomic physics.

PREREQUISITES
  • Understanding of the Rydberg formula

Hello all-

I am working to calculate the value of I3 for Li. I am working through the formula:

Z2hR/n2

Can anyone tell me what n is equal to? I had originally set n=3 since I am looking for I3, but it was marked incorrect as n should have been set at 1. I'm not sure why in this case

Thanks in advance.
