Question

Question 4 of 5 Map According to de Broglie's explanation of the Bohr atom, each possible electron orbit in a hydrogen atom corresponds to a particular standing wave pattern. In the figure at right is shown a diagram of an atom with two different electron orbits which have been "cut and unwrapped" to better show the electron waves. Suppose the standing wave pattern of the inner orbit is given in the figure. Sort the patterns below by whether or not they could be the standing wave pattern for the outer orbit.

Answer 1

If we sort the waves as:

1          4

2          5

3

According to the figure. The option 4 is not possible, because we do not have a complete wave, we have 3.5 waves in this case. The others are possible. In terms of the number of waves we have:

1-> 5 waves.

2-> 3 waves.

3-> 4 waves.

5-> 2 waves.

Outer orbits means greater energy and momentum. According to the de Bouglie's theory:

$\lambda = \frac{h}{p}$ ,

greater momentum means shorter wave lenght or more waves. In this sense, the order of the waves must be:

1st orbit -> 5.

2nf orbit-> 2.

3th orbit-> 3.

4th orbit-> 1.
