##### Computation of longest wavelength emission from $Ca^{19+}$
« on: November 19, 2021, 01:41:22 AM »
Was the following question correctly stated and correctly answered?

In Ca19+, how many electron shells are there? answer is n=1,2,3,4 Then in ground state how can we found its valence  electron in 6th shell or n=6?

Is Ca19+  one electron atom?

The question is correctly stated and correctly answered. (I haven't checked the calculations, but the method is right.)
n=6 is not the ground state but the 5th excited state (as the question says twice).
Is Ca19+ a one-electron atom? Do you really need to ask this? What is the atomic number of Ca? So how many electrons in a neutral Ca atom? How many in Ca19+?

Sorry for asking last question unnecessarily. Any way, thanks for your explanation.
