Problem: In the ground state of element 115, Uup, how many electrons have ms = -1/2 as one of their quantum numbers?

FREE Expert Solution

Recall: The magnetic spin quantum number ms can have a value of +1/2 or –1/2. If there are two anti-parallel electrons in an orbital, one of those two electrons has ms = – 1/2.

The atomic number of Uup is 115, so the neutral atom has 115 electrons. The electron configuration of Uup is: [Rn] 5f146d107s27p35f146d107p3
