Click the "set value" button. Now change the value of the quantum number, n,  by typing in the text box and then click the "set value" button again.

  1. Find the limits of the values you can type in the text box.
  2. Have you tried non-integer values?  If not, try a few.
  3. Why do you think these values have been chosen?
  4. Now try typing in "abcd". What happens?
