AI Generated Solution

To determine the increasing order of energies of the orbitals 4s, 3p, 4p, and 3d, we will use the n + l rule. This rule helps us to compare the energy levels of different orbitals based on their principal quantum number (n) and azimuthal quantum number (l). ### Step-by-Step Solution: 1. **Identify the Principal Quantum Number (n) and Azimuthal Quantum Number (l)**: - For each orbital, we need to identify the values of n and l. - **4s**: n = 4, l = 0 (since s = 0) - **3p**: n = 3, l = 1 (since p = 1) ...
