Periodic PropertiesHandwritten Notes
Periodic Properties is dense with trends and exceptions — atomic radius, ionisation enthalpy, electron affinity, electronegativity, and metallic character all carry anomalies that show up in JEE and NEET PYQs. These handwritten notes by Paaras Sir cover every trend with the anomalies highlighted.

Frequently Asked Questions
Are all anomalies in ionisation enthalpy covered?+
Yes — N vs O, Be vs B, and the second-period vs third-period exceptions are explained with the underlying electronic-configuration logic.
Do the notes cover diagonal relationship?+
Yes. Li↔Mg, Be↔Al, B↔Si diagonal relationships are tabulated with the property comparisons most likely to appear in MCQs.
Is the lanthanide contraction discussed?+
Yes — the cause and its consequences for the d-block (Zr/Hf similarity, decreasing basicity) are covered briefly here and expanded in the d & f Block chapter.
