UNIT 11 : S & P BLOCK ELEMENTS

S and P Block Elements is a substantial chapter in MDCAT Chemistry, sitting within the 25% Chemistry allocation (45 MCQs) of your 180-question paper.

What this chapter covers:

• Definitions of atomic radii, ionic radii, covalent radii, ionization energy, electron affinity, electronegativity, bond energy and bond length
• Recognition of the demarcation of the periodic table into S-block, P-block, D-block and F-block
• Reactions of Group I elements with water, oxygen and chlorine
• Reactions of Group II elements with water, oxygen and chlorine
• Reactions of Group IV Elements

This chapter is heavily conceptual and memorization-intensive rather than calculation-based, built on definitions, periodic trends, and a wide range of named reactions, minerals, compounds, and industrial processes.

Given the sheer number of distinct facts, trends, and exceptions packed into these subtopics, expect it to draw questions across the full 15% easy, 70% moderate, 15% difficult spread, with the moderate band dominated by trend-based reasoning and named-reaction recall.

Why this practice set helps:

• Covers every subtopic the PMDC curriculum identifies, plus the supporting concepts textbooks present alongside them
• Every question includes a full explanation of why the correct answer is right and why each other option is wrong
• Built to help you learn faster than passive reading, with nothing the exam may draw from left untouched

Work through this set attentively, and you build the precise recall and trend-based reasoning this fact-dense chapter demands.
