Modern Periodic Table — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Modern Periodic Table.

Identification of Period, Group, and Block for elements with higher atomic numbers (beyond Z=54)

high

NEET often tests the ability to apply electronic configuration rules to elements with higher atomic numbers, sometimes involving the f-block. Students need to be proficient in writing configurations for elements up to Z=118 and correctly determining their position. Questions might involve elements from the 6th or 7th period, requiring knowledge of f-orbital filling.

Conceptual questions on the 'anomalous pairs' and 'position of isotopes' as resolved by the Modern Periodic Table.

medium

While the direct basis (atomic number) is frequently asked, deeper conceptual questions comparing the Modern Periodic Table with Mendeleev's, specifically focusing on how it resolved historical issues, are valuable. These questions test understanding beyond mere recall and require analytical thinking about the implications of Moseley's work.

Questions linking electronic configuration directly to general properties of elements within a specific block or group.

high

The Modern Periodic Table is the foundation for periodic trends. Questions might ask about the metallic character, reactivity, or common oxidation states of an element based solely on its position or electronic configuration, without explicitly asking about periodic trends. This tests the integrated understanding of structure and property.
