When a gas is excited in an electrical discharge, light is emitted (this is essentially how neon lamps work). Niels Bohr looked at this emitted light using a spectrograph, which separates different wavelengths of light (just a like a simple triangular prism). Atoms, such as hydrogen or neon, emit very specific patterns of light. When you separate the wavelengths, you see a pattern of very sharp lines of light at only certain wavelengths and not others. In other words, the atoms emit only certain wavelengths of light, resulting in a series of lines when you look at the light through a spectrograph. Bohr looked at these lines and managed to figure out the pattern that determined which wavelengths were observed. He said that the light emitted was due to transitions between energy levels in the atoms, and the wavelength of light corresponded to the energy difference between the two states involved in the transition. In this way, he figured out the equation to predict the spacing between all of the energy levels of any one-electron atom or ion. His model was quite successful, and he was able to predict which lines you would see for things that hadn't even been measured yet (a good test for any theory!). Surprisingly, although he figured out the pattern so well, he didn't actually know what the patterns were really due to. In fact, he had to make assumptions that turned out to be completely false! However, despite these errors (which were corrected when quantum mechanics was developed), the Bohr model of the atom is very useful for many applications. His model does NOT work well for multi-electron atoms/ions, which unfortunately includes the large majority of atoms and ions! You need quantum mechanics for that!
yes, they are depicted by a red subatomic particle.
Neil Bohrs atomic model is simply called Bohrs model. It states that electrons have a certain amount of energy, so they must follow certain orbits. This is different from the modern atomic model.
The Bohr atomic model is similar to solar system.
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
Experiments like the photoelectric effect and atomic emission spectra provided evidence that electrons exist in discrete energy levels. These findings challenged the classical model of the atom, leading to Niels Bohr proposing his model in 1913 to explain the quantization of electron energy levels in atoms.

For a while, but eventually a new atomic model came out that we still use today.

There is no N in Bohrs. But his first name was Neils
The Bohr model!
No, Rutherford's model of the atom fails to explain the discrete spectral lines of elements. Bohr's model, which incorporates quantized energy levels and electrons moving in well-defined orbits, successfully explains the spectral lines of elements by linking them to the transitions between electron energy levels.
the planetary model
Niels Bohr devised the Bohr model, which depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus, with electrostatic forces providing attraction.http://en.wikipedia.org/wiki/Bohr_model
