In original Bohr model, two electrons are moving on the opposite sides of the nucleus. But this model is not consistent with the experimental value of the ground state energy. Please see the link "Bohr model helium" below. This model is just consistent with the experimental value.
Two electrons of Helium are not on the same circular orbital. The orbital planes of the two electrons are perpendicular to each other. By a computaional method, the length of both the two orbitals crossing perpendicularly is proved to be just 1 times de Broglie's wavelength when their total energy is consistent with the experimental value of Helium ground state energy. Please see Related links below to get the picture of a Bohr model of helium
No, the atomic model by Niels Bohr is only applicable to atoms or ions with only one electron.
The Bohr model for sulfur shows that sulfur has 16 electrons in total, with 2 in the first energy level, 8 in the second energy level, and 6 in the third energy level. The electrons in the outermost energy level are involved in chemical reactions.
In Niels Bohr's atomic model, he labeled a quantum number to describe the energy levels of electrons orbiting the nucleus. He called this quantum number "n," which represents the principal quantum number and determines the energy and size of the electron's orbit.
The Rutherford model proposed that an atom's positive charge is concentrated in a dense center called the nucleus. This model was based on the famous gold foil experiment conducted by Ernest Rutherford in 1909.
Bohr's model of the hydrogen atom works well for atoms with only one electron like hydrogen, but it fails for helium because helium has more than one electron. The model does not account for the repulsion between the two electrons in the helium atom, leading to inaccurate predictions of its behavior.
Niels Bohr in fact based his model on the hydrogen atom. However, I wouldn't say that the Bohr Model can be correctly applied to ANY atom. Whilst it is an excellent approximation it is not truly accurate. Please don't forget that the Bohr Model is just that, a model, and a model is never as accurate as the real thing.
The Bohr model of the atom was the first to propose that electrons orbit the nucleus in fixed paths or energy levels. This model was proposed by Niels Bohr in 1913, and it helped to explain the stability of atoms and the emission of specific frequencies of light.
Bohr proposed his model for the atom because (1) it easily explained spectral lines of hydrogen and (2) other models failed to do so. The model was accepted when it was successful in predicted spectral lines of ionized helium.
The Bohr model of the atom was a planetary model.
The Bohr model of the atom was a planetary model.
The atomic model of Bohr is not a quantum model.
Bohr's model explain the structure of mono electronic system
Neutrons were discovered in 1932, after the model of Bohr.

Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
The modern model of atom is quantic and is different from the Bohr model.
