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.
