Trends and Properties of Transition Elements
Explore trends in melting points, ionization enthalpy, atomic and ionic radii, and other physical and chemical properties across the d-block.
Why this shows up in the exam
You need to recognize and explain periodic trends and anomalies among transition elements.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Four successive members of the first row transition elements are listed below with their atomic numbers. Which one of them is expected to have the highest third ionisation enthalpy?
Push further
More challenging5 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
If relativistic effects were negligible for all elements, how would the physical state of mercury at room temperature most likely change, and why?
