What did Niels Bohr discover in physics?
Bohr was the first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element.
What makes Niels Bohr special?
Niels Bohr modeled the atom with electrons that could only have specific stable orbits. He was the first to apply the quantum concept, which restricts the energy of a system to certain discrete values, to the problem of atomic and molecular structure. For that work he received the Nobel Prize for Physics in 1922.
Did Niels Bohr prove Einstein wrong?
Einstein was the first physicist to say that Planck’s discovery of the quantum (h) would require a rewriting of the laws of physics. However, Einstein was right and Bohr proved to be wrong about light quanta.
What is Niels Bohr formula?
Bohr correctly proposed that the energy and radii of the orbits of electrons in atoms are quantized, with energy for transitions between orbits given by ∆E = hf = Ei − Ef, where ∆E is the change in energy between the initial and final orbits and hf is the energy of an absorbed or emitted photon.

What was Niels Bohr personality like?
One of the more interesting personalities of the early 20th century was Niels Bohr. Nevertheless, Bohr was always friendly, treated everyone with respect, and was revered in his later days by all physicists. He played a crucial role in helping scientists emigrate from Nazi Germany prior to and during World War II.
Did Niels Bohr contribute to the periodic table?
Niels Bohr applied his atomic theory to the periodic table of elements. He showed that chemical properties of an element resulted mainly from the behavior of valence electrons, the electrons occupying the highest stable orbit. This was an important step in the creation of the field of quantum chemistry.
