Quantum Numbers

What is the maximum number of electrons that can occupy a set of p-orbitals?

• 2

• 4

• 6

• 8

For the n = 4 energy level, what is the maximum possible value of l?

• 1

• 2

• 3

• 4

Which of the following is NOT a possible pair of quantum numbers?

• 2p

• 2d

• 4p

• 4f

Answer explanation

The correct choice is 2d because 'd' orbitals do not exist in the second principal energy level, making 2d an impossible pair of quantum numbers.

Which orbital shows a violation of the Pauli Exclusion Principle?

• A

• B

• C

• D

Answer explanation

Orbital A shows a violation of the Pauli Exclusion Principle as it can have two electrons with opposite spins, contrary to the principle.

Which of the following quantum number sets is not allowed?

• { 3, p, z, -1/2 }

• { 5, d, x, +1/2 }

• { 12, s , x, +1/2 }

• { 7, p, y, -1/2 }

Which set of Quantum numbers is not allowed

• (3,1,1,-1/2)

• (2,1,-2,+1/2)

• (4,2,-1,-1/2)
