WebOct 7, 2012 · Bohr became one of Denmark's most famous and acclaimed people and a central figure in 20th century physics. Work The discovery of the electron and radioactivity in the late 19th century led to different models being proposed for the atom’s structure. WebBohr published these ideas in 1913 to mixed reaction. Many people still hadn't accepted the idea of quanta, or they found other flaws in the theory because Bohr had based it on very simple atoms.
