How many orbitals are associated with an atom when n=5?
A) 4
B) 9
C) 16
D) 25
E) 36

Question

Quizplus · Accepted Answer

The total number of orbitals associated with an atom is given by the formula 2n^2, where n is the principle quantum number. When n=5, the number of orbitals is 2(5)^2 = 50. However, since we are only considering one atom and not a collection of atoms, we need to divide this by 2 to account for the fact that each orbital can hold two electrons with opposite spins. Therefore, the number of orbitals associated with an atom when n=5 is 25.
