# FIGURE Q39.4 shows the dot pattern of electrons landing on a screen. a. At what value or values of x is the electron probability density at maximum? Explain. b. Can you tell at what value or values of x the electron wave function c1x2 is most positive? If so, where? If not, why not?

a: x = -2, +2

b: x = -2, +2

See the step by step solution

## Concept used:

Wave function of electron gives the value of its probability density in a certain region.

## Part a:

At x = -2, +2

Because as it can be seen in the given image, most number of electrons hit the screen at these locations so these are the regions where electron probability density will be maximum.

## Part b:

The wave function will also be most positive at x = -2, +2 because wave function tells about distribution of probability density of electron.
