Text Solution

AI Generated Solution

To calculate the energy of the `Li^(+2)` atom for the second excited state, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Atomic Number (Z)**: - The atomic number of lithium (Li) is 3. Since we are dealing with `Li^(+2)`, we will use Z = 3 in our calculations. 2. **Determine the Principal Quantum Number (n)**: ...
