Which scientist said that electrons travel in paths called energy levels?

Which scientist said that electrons travel in paths called energy levels?

Niels Bohr
In 1913, Niels Bohr proposed that the electrons of an atom are at different energy levels. Each energy level is at a certain distance from the nucleus.

Who discovered the paths of electrons?

Thomson. Joseph John Thomson (JJ Thomson, 1856-1940; see photo at American Institute of Physics) is widely recognized as the discoverer of the electron.

Who proposed that electrons follow unpredictable paths around the nucleus?

One such example is the Electron Cloud model proposed by Erwin Schrödinger. Thanks to this model, electrons were no longer represented as particles moving around a central nucleus in a fixed orbit. Instead, Schrodinger proposed a model in which scientists could only make educated guesses about electron positions.

Who discovered that the trajectories of electrons cannot be predicted?

Scientist who contributed to modern atomic theory.

Question Answer
Electrons travel in certain paths, or energy levels. Bohr
Electrons can jump from one path in one level to one path in another. Bohr
Electrons are found in electron clouds, not in paths. Schrödinger and Heisenberg
The paths of the electrons cannot be predicted. Schrödinger

Who says electrons are scattered around the nucleus at a distance?

scientist Niels Bohr
He concluded that negatively charged particles are dispersed at a distance outside the nucleus. In 1913, the Danish scientist Niels Bohr proposed an improvement. He built on the concept that the mass of an atom is contained primarily in the nucleus.

How did we realize that an atom is mostly empty space?

How did he know that an atom was mostly empty space? He knew that an atom was composed mostly of empty space because most of the particles passed directly through the sheet.
