Formation of Ions
Students will understand how atoms gain or lose electrons to form positive and negative ions, achieving stable electron configurations.
Key Questions
- Explain why atoms form ions to achieve a full outer electron shell.
- Differentiate between cations and anions based on electron transfer.
- Predict the charge of an ion formed by elements in Groups 1, 2, 6, and 7.
