Understand the basic structure of atomic orbitals: s, p, d, and f orbitals have different numbers of orbitals. Specifically, s has 1, p has 3, d has 5, and f has 7 orbitals.
Recall the order of energy levels for orbitals: Generally, energy increases as you move from s to p to d to f within the same principal energy level. Additionally, energy increases with higher principal quantum numbers (n).
Evaluate statement a: A set of d orbitals contains 5 orbitals. This is true based on the known structure of atomic orbitals.
Evaluate statement b: A set of 4s orbitals would have more energy than a set of 3p orbitals. This is false because 4s orbitals are filled before 3p orbitals, indicating they have lower energy.
Evaluate statement d: A set of f orbitals contains 3 orbitals. This is false because a set of f orbitals actually contains 7 orbitals.
