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, third, and fourth squares is a pair of upwards and downwards pointing arrows. the fifth square has a single upwards pointing arrow.

based on the diagram, what values can be assigned to the principal quantum number for the electrons in the atom? what information does this quantum number provide about the location of the electron?

1)Thus based on the diagram , the values of principle quantum number that can be assigned to the electrons are : 2,3 and 4.

2)This quantum number tells us the shell in which an electron is present and how far it is roughly from the nucleus.

Explanation:

According to the rules of electron filling in subshells in quantum mechanics , Aufbau's principle states that :

"An electron must be filled in a lower energy state or subshell and then higher. If they have the same energy , the one with lesser principal quantum number will be filled first."

Thus ,

The series of filling goes like:

Thus , the subshells in the given information have 1,3 and 1 orbitals respectively. Thus it has to be which is possible in two cases :

1)Thus based on the diagram , the values of principle quantum number that can be assigned to the electrons are : 2,3 and 4.

2)This quantum number tells us the shell in which an electron is present and how far it is roughly from the nucleus.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
