The correct Answer is:
To find the values of quantum numbers for 2p orbitals, we will follow these steps: ### Step 1: Identify the Principal Quantum Number (n) The principal quantum number (n) indicates the energy level or shell of an electron. For the 2p orbital: - The value of n is **2**. ### Step 2: Determine the Azimuthal Quantum Number (l) The azimuthal quantum number (l) defines the shape of the orbital. For p orbitals: - The value of l is **1** (since l = 0 for s, l = 1 for p, l = 2 for d, etc.). ### Step 3: Compile the Quantum Numbers For the 2p orbital, we have: - n = 2 - l = 1 ### Step 4: Conclusion Thus, the values of quantum numbers for the 2p orbitals are: - n = 2 - l = 1 ### Final Answer The quantum numbers for 2p orbitals are: - n = 2 - l = 1 ---
