Bohr structure
WebBy convention, elements are organized in the periodic table, a structure that captures important patterns in their behavior.Devised by Russian chemist Dmitri Mendeleev (1834–1907) in 1869, the table places elements into columns—groups—and rows—periods—that share certain properties.These properties determine an element’s … WebIn 1913 Bohr proposed a model of the atom, giving the arrangement of electrons in their sequential orbits. ... had followed the Atombau structure of electrons instead of Bohr who was familiar with the chemists' views of electron structure, spoke of Bohr's 1921 lecture and 1922 article on the shell model as "the greatest advance in atomic ...
