Long Form of Periodic Table — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Long Form of Periodic Table.

Identification of Period, Group, and Block for elements with Z > 54

high

While elements up to Z=54 are commonly tested, NEET often includes questions for elements in the 6th or 7th period, which involve d- and f-orbital filling. Students need to be proficient in writing configurations for these elements, including exceptions like Cr and Cu, and then correctly applying the rules for period, group, and block determination. This tests a deeper understanding of electronic configuration beyond just the initial periods.

Application of IUPAC nomenclature for elements with Z > 100, including their predicted block/group.

IUPAC nomenclature is a standard factual recall topic. A slightly more advanced question could ask for the IUPAC name and then, based on its atomic number, ask to which block or group it would belong. For example, 'What is the IUPAC name of the element that would be a p-block element in Period 7, Group 18?' (Ununoctium, Z=118). This combines two concepts.

Conceptual questions on the rationale behind the periodic table's structure and anomalies.

medium

Beyond simple recall, NEET could ask why f-block elements are placed separately, or the significance of atomic number over atomic mass. Questions might also probe the exceptions to general trends or the reasons for specific properties of a block (e.g., why transition metals show variable oxidation states). This tests analytical understanding rather than rote memorization.
