could you please give me answers for this 10 questions and I'll mark as briliantlist
Answers
Answer:
1. 1922
2. stationary
3. hydrogen
4. for the effect of magnetic field (Zeeman effect) or electric field (Stark effect) on the spectra of atoms
5. which suggested that electrons travel in elliptical orbits around a nucleus instead of the Bohr model's circular orbits.
6. ground state
7. a-q b-r c-p
8. The Bohr model failed because it failed to take into account one thing: synchrotron radiation.
It could not explain the distribution and arrangement of electrons in atoms. Sommerfeld's model was unable to explain the spectra of alkali metals such as sodium, potassium etc.
9. An emission line will appear in a spectrum if the source emits specific wavelengths of radiation. This emission occurs when an atom, element or molecule in an excited state returns to a configuration of lower energy.
10. In quantum mechanics, an excited state of a system (such as an atom, molecule or nucleus) is any quantum state of the system that has a higher energy than the ground state (that is, more energy than the absolute minimum).
