In accordance with Bohr's theory, the K.E of the electron is equal to:
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
In Bohr's model, the kinetic energy of an electron is given by ½ × (Ze² / r), where Z is the atomic number, e is the electron charge, and r is the radius of the orbit. It's positive, representing the energy of motion of the electron around the nucleus.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
