Step 1:I'll solve this step-by-step, following the LaTeX formatting guidelines precisely:
Step 2:: Determine the atomic number of nitrogen
- Its neutral atomic configuration is $$1s^{2} 2s^{2} 2p^{3}
- Nitrogen is element 7 on the periodic table
Step 3:: Calculate the number of electrons for a nitride ion
- Nitride ion has a 3− charge - This means it gains 3 additional electrons - Neutral nitrogen has 7 electrons - Nitride ion will have 7 + 3 = 10 electrons total
Step 4:: Write the electron configuration for N³⁻
- $$1s^{2} 2s^{2} 2p^{6}
- Fill orbitals systematically from lowest to highest energy
Step 5:: Verify the configuration
- $$2p^{6}$$ (6 more electrons)
- 2s^{2} (2 more electrons) - Total: 10 electrons - Matches the expected configuration for N³⁻
Final Answer
The electron configuration of a nitride ion N³⁻ is 1s^{2} 2s^{2} 2p^{6}.
