In a single hydrogen atom, the electron is excited to its 6th orbit. The maximum no. of distinct lines possible, when it comes to the ground state is:
Correct answer: B. 15
- A. 12
- B. 15
- C. 5
- D. 22
Explanation
The maximum number of emission lines when the excited electron of a H atom in n = 6 drops to the ground state is 2(n−n)(n−n+1) = 25×6 =15 lines.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
