Structure of Atom

If the radius of the second Bohr orbit of the $H e^{+}$ ion is 105.8 pm, what is the radius of the third Bohr orbit of the $L i^{2 +}$ ion?

A.158.7 Å
B.158.7 pm✓
C.15.87 pm
D.1.587 pm

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
