Niels Bohr (1885-1962) studied and adapted the works of Heisenberg, Planck, and others who investigated the particle and wave concepts of matter and energy. He was one of the earliest to work on quantum mechanics, which addressed the particle concept of energy. He disagreed with Einstein over the concept of the photon.
Bohr developed the simplest concept of electron orbitals, where negatively-charged electrons circle a positively charged nucleus. His 1913 model defined energy states and the concept of electron energy levels (now defined by the quantum theory, electron clouds, and valence shells). He won the 1922 Nobel Prize in Physics.

When did Niels Bohr come up with his Bohr model?
The Bohr model was made around 1913. There isn't an exact date, it's unknown.
How tall was Niels Bohr?
Niels Bohr was sub-atomic in height. This is how he figured out how atoms work. Wolfgang Pauli was even smaller, which is how he knew about electrons. They teamed up for a film in the twenties, but no one could see them. It was merely postulated that they were there.
How did niels bohr change the current view of the atom?
Neils Bohr changed the current view of the atom by adding a nucleus with made up of protons and neutrons.
Was niels bohr the first to come up with the atom?
No. Ancient Greek philosophers postulated the existence of atoms.In 1803, John Dalton proposed an atom to explain chemical reactions that had been observed by scientists since the 1800's.
What areas did Niels Bohr make contributions in?
He made a model of the atom, with electrons circling the nucleus.

Niels Bohr
Who is credited with coming up with the modern periodic table?

Who discovered electrons travel in certain paths or energy levels?
He came up with his model of the hydrogen atom, containing this idea, in 1913. That's almost exactly 100 years ago. Neils Bohr came from Denmark and they will be celebrating this centenary, in Denmark.
Facts about what Niels Bohr was known for?
Niels Henrik David Bohr (October 7, 1885 - November 18, 1962) was a Danish physicist who made fundamental contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. He was also part of the team of physicists working on the Manhattan Project. Bohr married Margrethe Nørlund in 1912, and one of their sons, Aage Niels Bohr, grew up to be an important physicist, who like his father received the Nobel prize, in 1975.

What was Ernest Rutherford's an Niels Bohr's most famous discovery?
The short answer is that Ernest Rutherford discovered the nucleus of the atom and was a mentor to Niels Bohr who further refined the model by showing that the nucleus was made up of neutrons and protons. The existence of electrons had already been inferred earlier. Ernest Rutherford opened the door to the field of nuclear physics whereas Niels Bohr's contributions pointed the way to quantum physics. At the time, it was noted that the nucleus within the atom takes up about as much space as a fly in a cathedral. Since then, it has been shown that the subatomic particles are themselves made up mostly of vast empty spaces containing tiny specs of something that may be described as either energy or matter or neither and both.
Who developed the model of an atom as a build up of successive orbital shells of electrons?
J.J Thompson discovered the electron during his famous cathode ray tube experiment in 1897, but it was actually Niels Bohr who discovered the electron shell (by accident), performing an x-ray experiment in 1909.
What is the atomic theory of neils bohr?
An atomic theory that patches up the holes in Ernest Rutherford's own. Bohr's theory states that electrons give off energy in bunches, not continously, so as long as the electrons remain in a stable orbit they will have the same amount of energy.
