KCET Atoms Weightage 2025

KCET Atoms Weightage 2025 is expected to be approximately 3-4 % of the weightage of the Physics Section.  Candidates can expect 2 to 3 questions on this topic in the KCET 2025 exam. The Atoms chapter includes Rutherford's Atomic Model, Emission and Absorption Spectra, Bohr’s Model of the Hydrogen Atom, De Broglie’s Hypothesis, Energy Levels and Transitions etc. Candidates aspiring to appear for the KCET 2025 exam should ace the Atoms chapter. To master the KCET Atoms questions, it is always suggested to focus on solving conceptual questions, and numerical problems, along with the theory-based questions.

To score good marks in the KCET 2025 exam, candidates must thoroughly comprehend the KCET syllabus 2025 . Attempting the KCET Previous Year Question Papers will help candidates increase their chances of achieving good scores in the KCET 2025 exam .

KCET Atoms Sample Questions

Candidates can check some of the sample KCET Atoms questions as provided below.

1. If a hydrogen atom emits a photon of energy 10.2 eV, what is the initial and final energy level of the electron?
2. Which spectral line in the Balmer series corresponds to a transition from n=4n = 4n=4 to n=2n = 2n=2? (Understanding of emission lines and their wavelengths is needed.)
3. What is the radius of the second orbit of a hydrogen atom according to Bohr’s model? (Options might include different multiples of the Bohr radius.)
4. An alpha particle is fired towards a gold foil in Rutherford’s experiment. If it deflects by 180°, what does this indicate about the nature of the atomic nucleus?
5. Calculate the energy of the photon emitted when an electron in a hydrogen atom transitions from n=3 to n=2.
