The Quantum number of the electron isn=6

Step by step solution

01

Step: 1 Given information

3.0-nm-long one-dimensional box if the electron's de Broglie wavelength is 1.0nm

02

Step: 2 Calculation 

We can start the solution with expression for de Broglie wavelength of a particle in a box:

λ=2Lnn=2Lλnn=2·3·10-91·10-9n=6
