Quantum mechanics predicts that in the hydrogen atom, all orbitals with the same value of n (e.g., the three 2p orbitals) are degenerate, meaning:
A) that they have similar looking shapes.
B) that they are similarly oriented in space.
C) that they have the same frequency.
D) that they have the same wavelength.
E) that they have the same energy.
