In what model would electrons be able to orbit at any distance from the nucleus?
However, unlike planets revolving around the sun—which can theoretically orbit at any distance whatsoever from the sun—electrons in the Bohr model can orbit only at specific, fixed distances from the nucleus.
What is Schrodinger’s model?
Erwin Schrodinger. A powerful model of the atom was developed by Erwin Schrödinger in 1926. The Schrödinger model assumes that the electron is a wave and tries to describe the regions in space, or orbitals, where electrons are most likely to be found.
Who suggested that electrons orbit the nucleus at specific distances?
Niels Bohr
In 1913, Niels Bohr revised Rutherford’s model by suggesting that the electrons orbited the nucleus in different energy levels or at specific distances from the nucleus.
Where are the electrons found in Bohr’s atomic model?
the nucleus
In the Bohr model of the atom, electrons travel in defined circular orbits around the nucleus.
Why was Bohr model accepted?
His model identified more clearly where electrons could be found. Although later scientists would develop more refined atomic models, Bohr’s model was basically correct and much of it is still accepted today. It is also a very useful model because it explains the properties of different elements.
What is the current model of the atom?
The modern model of atomic structure is called the “electron cloud” model. Edwin Schrodinger, an Austrian physicist, proposed that electrons do not travel in static, or fixed paths. The two atomic models most commonly used are the Bohr model and the electron cloud (Quantum Mechanics) model.
What is the electron model of the atom?
The model states that electrons in atoms move in circular orbits around a central nucleus and can only orbit stably in certain fixed circular orbits at a discrete set of distances from the nucleus. These orbits are associated with definite energies and are also called energy shells or energy levels.
What do electrons orbit around the nucleus called?
Electrons in atoms orbit the nucleus. The electrons can only orbit stably, without radiating, in certain orbits (called by Bohr the “stationary orbits”) at a certain discrete set of distances from the nucleus. These orbits are associated with definite energies and are also called energy shells or energy levels.
What is the Bohr model of the hydrogen atom?
In atomic physics, the Bohr model depicts an atom as a small, positively charged nucleus surrounded by electrons. These electrons travel in circular orbits around the nucleus—similar in structure to the solar system, except electrostatic forces rather than gravity provide attraction. The Bohr atom The Rutherford–Bohr model of the hydrogen atom.
What is the significance of the planetary model of the atom?
In terms of electron emission, this would represent a continuum of frequencies being emitted since, as the electron moved closer to the nucleus, it would move faster and would emit a different frequency than those experimentally observed. These planetary models ultimately predicted all atoms to be unstable due to the orbital decay.
