![]() ![]() Bohr would come to apply this idea philosophically as well, with the belief that evolving concepts of physics deeply affected human perspectives. The concept asserted that physical properties on an atomic level would be viewed differently depending on experimental parameters, hence explaining why light could be seen as both a particle and a wave, though never both at the same time. ![]() He worked with Werner Heisenberg and other scientists on a new quantum mechanics principle connected to Bohr's concept of complementarity, which was initially presented at an Italian conference in 1927. Wins Nobel Prizeīohr received the 1922 Nobel Prize in Physics for his work on atomic structures, and he would continue to come up with revolutionary theories. Then, in 1920, he founded the university’s Institute of Theoretical Physics, which he would head for the rest of his life. Though Bohr's discovery would eventually be tweaked by other scientists, his ideas formed the basis of future atomic research.Īfter teaching at Manchester’s Victoria University, Bohr settled again at Copenhagen University in 1916 with a professorship position. The couple would have six children four survived to adulthood and one, Aage, would become a well-known physics scientist as well.īohr’s own research led him to theorize in a series of articles that atoms give off electromagnetic radiation as a result of electrons jumping to different orbit levels, departing from a previously held model espoused by Ernest Rutherford. During the fall of the same year, Bohr traveled to Cambridge, England, where he was able to follow the Cavendish Laboratory work of scientist J.J. The young Bohr eventually attended Copenhagen University, where he received his master's and doctorate in physics by 1911. Niels Bohr was born on October 7, 1885, in Copenhagen, Denmark, to mother Ellen Adler, who was part of a successful Jewish banking clan, and father Christian Bohr, a celebrated physiology academic. He won the 1922 Nobel Prize in physics for his ideas and years later, after working on the Manhattan Project in the United States, called for responsible and peaceful applications of atomic energy across the world. ![]() However, his model worked well as an explanation for the emissions of the hydrogen atom, but was seriously limited when applied to other atoms.Niels Bohr was an accomplished physicist who came up with a revolutionary theory on atomic structures and radiation emission. ![]() Moving up the ladder increases your potential energy, while moving down the ladder decreases your energy.īohr's work had a strong influence on our modern understanding of the inner workings of the atom. As you move up or down a ladder, you can only occupy specific rungs and cannot be in the spaces in between rungs. An everyday analogy to the Bohr model is the rungs of a ladder. The electron is not allowed to occupy any of the spaces in between the orbits. The orbits that are further from the nucleus are all of successively greater energy. The ground state of the hydrogen atom, where its energy is lowest, is when the electron is in the orbit that is closest to the nucleus. When the electron is in one of these orbits, its energy is fixed. It accounts for a wide range of physical phenomena, including the existence of discrete packets of energy and matter, the uncertainty principle, and the exclusion principle.Īccording to the Bohr model, often referred to as a planetary model, the electrons encircle the nucleus of the atom in specific allowable paths called orbits. This is a theory based on the principle that matter and energy have the properties of both particles and waves. This was the basis for what later became known as quantum theory. When the energy is removed, the electrons return back to their ground state, emitting a corresponding amount of energy-a quantum of light, or photon.
