The atomic Bohr model consist in a positive nucleus surrounded by electrons in a continuous movement.
I Don't Know. Get up and go ask somebody who actually knows this answer.
Niels Bohr invented the bohr diagram.
Now, an advanced model derived from the Niels Bohr theory.
Frank Bohr is 6' 3".
the bohr model for hydrogen is H
Yes

Example of scientists: Dalton, Thomson. Rutherford, Bohr etc.
Niels Bohr (the father, not the son who also got a Nobel prize) is known for: - Nuclear models with layers explaining radiation - Contributions to quantum mechanics
Because Bohr's model was wrong. As physics progressed it was quickly realized that his model did not fit what was actualy happening so new models were created.
Niels Bohr created the Bohr Model of the atom. It was an improvement on previous models (Thompson's Plum Pudding Model, Rutherford's model, etc.) which depicted the atom as a positive nucleus surrounded by negative electrons. Niels Bohr was also a member of the team of scientists working on the Manhattan Project.
Bohr's atomic model was based upon a famous experiment by Rutherford, who determined that an atom has a small, dense, positively charged nucleus surrounded by negatively charged electrons. Bohr took this information and came up with a "planetary" model where electrons orbit the nucleus in set paths, much like the planets orbit the sun. We now know this is inaccurate, but Bohr's model is still used in teaching because it's a handy way to keep track of how many electrons are in which energy level.
Bohr diagrams are useful models to show the count - and loosely, the arrangement - of electrons by shell.

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.
