To determine the number of orbitals in the third energy level, we can follow these steps: ### Step 1: Identify the Principal Quantum Number The principal quantum number (n) indicates the energy level of an electron in an atom. For the third energy level, n = 3. ### Step 2: Use the Formula for Number of Orbitals The number of orbitals in a given energy level can be calculated using the formula: \[ \text{Number of orbitals} = n^2 \] ...
