Bohr’s first contribution to the emerging new idea of quantum physics started in 1912, in a substantive trilogy of articles published in The Philosophical Magazine in 1913, that electrons could only occupy particular orbits determined by the quantum of action and that electromagnetic radiation from an atom occurred only when an electron jumped to a lower-energy orbit. Although radical and unacceptable to most physicists at the time, the Bohr atomic model was able to account for an ever-increasing number of experimental data, famously starting with the spectral line series emitted by hydrogen.
Already in his 1913 trilogy, Bohr had sought to apply his theory to the understanding of the periodic table of elements. He improved upon that aspect of his work into the early 1920s, by which time he had developed an elaborate scheme building up the periodic table by adding electrons one after another to the atom according to his atomic model.
Our posters are a great addition to any science geeks home, printed on durable archival paper with a matt finish our prints look great on any wall. With a 0.5 inch border, these prints are perfect for framing. Our posters ship in a protective waterproof sleeve in a rolled tube for added protection.
