KCET Atoms Sample Questions
Candidates can check some of the sample KCET Atoms questions as provided below.
- If a hydrogen atom emits a photon of energy 10.2 eV, what is the initial and final energy level of the electron?
- 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.)
- 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.)
- 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?
- Calculate the energy of the photon emitted when an electron in a hydrogen atom transitions from n=3 to n=2.
