Answer:
The correct option is: (D) All of the above
Explanation:
An atomic orbital is the three-dimensional space or region around the nucleus of an atom, where the probability of finding an electron is maximum.
The s-orbitals are the atomic orbitals that have azimuthal quantum number, l = 0. These atomic orbitals have spherical shape and symmetry.
The p-orbitals are the atomic orbitals that have azimuthal quantum number, l = 1. These atomic orbitals have a dumbbell shape.
The atomic orbitals that are closer to the nucleus, have lower energy. Therefore, we can say that the s-orbitals are lower in energy than the p-orbitals.
