Expert Answer:

Given colon

Diameter space equals space 20 space nm

Radius space equals space 10 space nm.
space space space space space space space space space space space equals 10 cross times 10 to the power of negative 9 end exponent space straight m

We space have comma

Bohr space radius space equals space 0.529 space straight n squared cross times space 10 to the power of negative 10 end exponent space

10 cross times 10 to the power of negative 10 end exponent space space equals space 0.529 space straight n squared cross times space 10 to the power of negative 10 end exponent space

space space space space space space space space space space space space space space straight n squared space equals space fraction numerator 10 cross times 10 to the power of negative 9 end exponent space over denominator space 0.529 space straight n squared cross times space 10 to the power of negative 10 end exponent end fraction

space space space space space space space space space space space space space space space space space space space equals space 189.90

space space space space space space space space space space space space space space space space straight n space almost equal to space 14 space
 
Principle quantum number is 14.
