What discoveries led up to niels bohr model?
Before Niels Bohr's model, discoveries such as Max Planck's quantization of energy and Albert Einstein's explanation of the photoelectric effect helped pave the way for understanding the behavior of atoms. Additionally, Ernest Rutherford's nuclear model of the atom, which proposed a dense nucleus surrounded by orbiting electrons, was another key advance that influenced Bohr's model.
What areas did Niels Bohr make contributions in?
He made a model of the atom, with electrons circling the nucleus.
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.
Who came up with the concept of energy levels?
The concept of energy levels in atoms was developed by Niels Bohr in 1913 as part of his atomic model. Bohr proposed that electrons orbit the nucleus in specific energy levels, and that they need a specific amount of energy to jump between these levels.
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.

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

Which scientist developed atomic model?
John Dalton developed the first modern atomic theory in the early 19th century, proposing that elements are made up of tiny, indivisible particles called atoms. Later, Ernest Rutherford's gold foil experiment in 1911 led to the discovery of the nucleus and the planetary model of the atom.
Did niels Bohr come up with anything?
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.
How was Niels Bohr childhood?
Niels Bohr was born in 1885, 7 October, second born of Christian Bohr and Ellen Adler Bohr. He had a younger brother Harald and an older sister, Jenny. Nies liked to play football together with his brother. He started school at seven and attended Gammelholm Latin School.
