Group 13 Elements: Properties and Trends
Study the trends in atomic radii, oxidation states, inert pair effect, electron deficiency, Lewis acidity, and anomalous behavior of boron in group 13 elements.
Why this shows up in the exam
NEET and JEE often test your understanding of periodic trends, stability, and unique behaviors within group 13.
How NEET tests this
