All of the following were theorised by Bohr in his description of the atom except
Correct answer: D. Electrons radiate energy continuously in a given orbit
- A. Angular momentum of electrons in multiples of h/2π
- B. Electrons revolve in discrete circular orbits
- C. Energy of each electron is directly proportional to n^2
- D. Electrons radiate energy continuously in a given orbit
Explanation
Bohr's atomic model, proposed in 1913, theorized that electrons in orbits would continuously radiate energy, leading to their spiralling into the nucleus. However, this idea contradicted experimental observations and was later revised with the development of quantum mechanics. In reality, electrons in stable orbits do not continuously radiate energy, as explained by the principles of quantum theory.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
