Sample Electron Configuration Explained
Example: Neon (Atomic Number 10)
Let's analyze how the answer key guides students to write the electron configuration for neon.
- Identify the total number of electrons: 10.
- Determine the order of orbital filling: 1s, 2s, 2p, 3s, etc.
- Fill the orbitals according to the Aufbau principle:
- 1s² (2 electrons)
- 2s² (2 electrons)
- 2p⁶ (6 electrons)
- Combine to write the full configuration: 1s² 2s² 2p⁶.
Using the Answer Key for Verification
The answer key confirms that neon's electron configuration is correctly written as 1s² 2s² 2p⁶. If a student writes 1s² 2s² 2p⁵, the answer key highlights the mistake—perhaps an oversight of the total electrons or the orbital filling order—and guides correction.
Advanced Concepts and Electron Configuration Variations
Noble Gas Shortcut Notation
To simplify electron configuration writing, especially for larger atoms, the answer key demonstrates the use of noble gas notation:
- Replace the inner core configuration with the noble gas symbol in brackets.
- For example, phosphorus (atomic number 15): [Ne] 3s² 3p³.
Electron Configurations of Ions
The answer key also covers how to write electron configurations for ions, which involves adding or removing electrons from neutral atom configurations. For instance:
- Sodium ion (Na⁺): electron configuration of Na (11 electrons): 1s² 2s² 2p⁶ 3s¹. Removing one electron gives 1s² 2s² 2p⁶.
- Chloride ion (Cl⁻): electron configuration of Cl (17 electrons): 1s² 2s² 2p⁶ 3s² 3p⁵. Adding one electron gives 1s² 2s² 2p⁶ 3s² 3p⁶.
Conclusion: Maximizing Learning with the Answer Key
The Gizmo Student Exploration Electron Configuration Answer Key is an essential tool for mastering atomic structure concepts.
