Respuesta :
Neil Bohr contributed towards science in many ways, but his contributions did not include the charge of an electron. Neil Bohr recognized a relationship between the chemical properties of a substance and the number of valence shell electrons. Moreover, he introduced the atomic model in 1913 and provided the liquid-drop model to explain nuclear fusion.
Answer: The charge of an electron
Explanation:
The charge on electrons was determined by the Robert Millikan and Harvy Fletcher from their experiment named Oil drop experiment.
The charge on the electrons is [tex]-1.602\times 10{-19} Coulombs[/tex]
Whereas Neil Bohr in his structure of atom explained that:
- Electrons are moving around the nucleus in a discrete circular paths known as orbits or shells.
- These orbitals or shells have fixed value of energy.
- Emission spectra of hydrogen.
