The complete orbital notation diagram of an atom is shown. Five squares are shown aligned horizontally. Inside the first square
from the left is shown one upwards pointing arrow and one downwards pointing arrow. In the second square is another pair of upwards and downwards pointing arrow. Inside the third square is another pair of upwards and downwards pointing arrow. Inside the fourth square is another upwards and downwards pointing arrow. Inside the fifth square is an upwards pointing arrow. Based on the diagram, what values can be assigned to the angular momentum quantum number for the electrons in the atom? What information does this quantum number provide about the location of the electron?
1 answer:
Answer:
l = 0, 1, and 2; it is in a d orbital.
Explanation:
1. Angular momentum quantum number
One square means l = 0.
Three squares mean l = 1.
Five squares mean l = 2.
If an atom contains electrons with l = 2, it must also have electrons with l = 0 and 1.
Thus, the electrons in the atom can be assigned the angular momentum quantum numbers l = 0, 1, and 2.
Those in a set of five squares all have l = 2.
2. Location of electron
The last electron is the lone electron in the fifth square. Since l = 2, the electron is in a d orbital.
