Chemistry - Structure of Atom
Practise 24 VITEEE previous year questions on Structure of Atom, compiled from papers spanning 2008 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty VITEEE tests.
Structure of Atom has been asked in 13 of the 18 years of VITEEE papers analysed (2006–2024), with 24 questions in all. 63% of them were easy, 33% moderate and 4% tough. Most of its questions came from 2019, with 3 questions that year. In the last three years (2022–2024) it had 3 questions across 3 papers, about 1 per paper.
The chapter's 7 topics are not weighted equally: Dual Behaviour of Matter and Heisenberg Uncertainty Principle (8 questions, 33%), Bohr's model (5 questions, 21%), and Quantum mechanical model (4 questions, 17%) have been asked the most. Over the last five years the most frequent topics have been Atomic Mass and Atomic Size (2), Atomic Models (1), and Dual Behaviour of Matter and Heisenberg Uncertainty Principle (1). Atomic Models has produced the most tough questions (1).
