Скачать или смотреть Ionic Radii MCQ Explained | N³⁻ O²⁻ F⁻ Comparison | A/L Chemistry Model Paper Discussion

Understanding ionic radii is a key requirement for G.C.E. A/L Chemistry MCQs.
In this video, I clearly explain a Model paper question comparing the ionic radii of N³⁻, O²⁻, and F⁻.

You’ll learn:
1. Why are these ions isoelectronic
2. How nuclear charge affects ionic size
3. The correct order of ionic radii
4. Common student mistakes in MCQs
5. How to answer similar questions confidently in the exam

This is a must-watch explanation for A/L Chemistry students, especially if you are aiming for A or B grades.

🎯 Who should watch this?
✔ A/L Chemistry students
✔ Repeat students & private candidates
✔ Students struggling with Atomic Structure & Spectra
✔ Anyone preparing for MCQs & structured questions
