If r is the radius of first orbit, the radius of nth orbit of H-atom is given by:
Correct answer: A. rn2
- A. rn2
- B. r/n
- C. rn
- D. r2n2
Explanation
The correct option is AAccording to Bohr's Model:r ∝n2/ZSo, radius of nth orbit is rn=rn2, as Z=1 for H atom.

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.
