Three connected modules — Periodic Trends, Properties Reference, and the Anomaly Atlas.
Stop memorising the periodic table. Start understanding where it breaks — trends, ranked properties, and the trap MCQs examiners actually test.
Three connected modules — Periodic Trends, Properties Reference, and the Anomaly Atlas.
The highest-yield corner of Class 11 inorganic chemistry, drilled by causality — not rote.
Interactive table — toggle any property and a single arrow shows exactly which way it grows. The whole cheat-sheet in one glance.
Every property ranked by predictive power, tabulated with units, drivers and break-points, traced back to effective nuclear charge & shielding.
42 trap MCQs written around the exact misconceptions trends hide — each with a worked answer and why every wrong option is wrong.

Velans Chemistry is a focused, offline study companion for the periodic properties — the highest-yield, most-tested corner of Class 11 inorganic chemistry. Three connected modules take you from the trends, to the ranked reference, to the exceptions examiners actually test.
An interactive periodic table: switch on any property — atomic radius, electronegativity, ionisation energy, electron affinity, metallic character, reactivity — and a single arrow shows exactly which way it grows across the elements.
Every periodic property ranked by predictive power and tabulated with units, causal factors, and break-points — plus a relationship map tracing them all back to the two variables that cause almost everything: effective nuclear charge and shielding. Five tabs: significance, trends, drivers, map & insight, applications.
The exceptions, drilled. A ranked cheat-sheet of the periodic-table anomalies that matter, 42 trap MCQs written around the exact misconceptions the trends hide — each with a worked explanation AND why every wrong option is wrong — and a revision deck that rebuilds the logic from first principles.
