Problem: Imagine a universe in which the value of ms can be +1/2, 0, and -1/2. Assuming that all the other quantum numbers can take only the values possible in our world and that the Pauli exclusion principle applies, give the following.the new electronic configuration of neon

FREE Expert Solution

We’re being asked to determine the new electronic configuration of neon.


We’re going to determine the quantum numbers for the single valence electron of copper using the following steps:

Step 1. Define and determine the possible values of the quantum numbers.
Step 2
Determine the new electron configuration of the Neon atom.


Step 1. Define and determine the possible values of the quantum numbers.

principal quantum number (n)  energy level in orbitals and its value could be any positive integer starting from 1 to infinity.
angular momentum quantum number (ℓ) → (l) has to be at least 1 less than n, range of values from 0 up to (n-1)

▪ Each ℓ value corresponds to a subshell:

 = 0 → s subshell
 = 1 → p subshell 
 = 2 → d subshell
 = 3 → f subshell

• magnetic quantum number (m) → range of values from - to + 

▪ The m values (for each ℓ) represent an orbital for the subshell:
