How many different values of l are possible for an electron with principal quantum number n = 4? express your answer as an integer?

The number of elements in a quantum is the count of 0 to n - 1 where n is the principal quantum number. There are 4 different values of i in quantum number n =4.

Given that:

-- quantum number

To count the quantum numbers (i), we make use of the following set:

The value of n is:

So, the set will be populated as follows

The number of elements in the set is 4.

This means that there are 4 different values of i

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
