The correct Answer is:
To solve the problem, we need to match the electronic configurations with the correct elements. Here’s a step-by-step breakdown: ### Step 1: Analyze the Given Electronic Configurations We have the following electronic configurations to match with their respective elements: 1. **5s¹ 4d⁵** 2. **6s¹ 5d¹⁰** 3. **4s¹ 3d¹⁰** 4. **5s⁰ 4d¹⁰** ### Step 2: Identify the Elements and Their Electronic Configurations Now, let's identify the electronic configurations of the elements provided: - **Copper (Cu)**: Atomic number 29 - Configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁹ → 4s¹ 3d¹⁰ (due to stability) - **Palladium (Pd)**: Atomic number 46 - Configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ → 5s⁰ 4d¹⁰ (due to stability) - **Molybdenum (Mo)**: Atomic number 42 - Configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ → 5s¹ 4d⁵ (due to half-filled stability) - **Chromium (Cr)**: Atomic number 24 - Configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁴ → 4s¹ 3d⁵ (due to half-filled stability) - **Gold (Au)**: Atomic number 79 - Configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ → 6s¹ 5d¹⁰ (due to stability) ### Step 3: Match the Configurations to the Elements Now we can match the configurations: 1. **5s¹ 4d⁵** → **C) Mo (Molybdenum)** 2. **6s¹ 5d¹⁰** → **E) Au (Gold)** 3. **4s¹ 3d¹⁰** → **A) Cu (Copper)** 4. **5s⁰ 4d¹⁰** → **B) Pd (Palladium)** ### Final Matches - 1 → C (Mo) - 2 → E (Au) - 3 → A (Cu) - 4 → B (Pd) ### Conclusion The correct matches are: - 1C, 2E, 3A, 4B.
