Water on Extrasolar Planets In early April 2007 astronomers announced the discovery of water on a planet orbiting the star, HD 209458. How is it possible to detect water on an extrasolar planet? spectroscopy • extrasolar planet • astronomical • infrared • hd 209458b
Spectroscopy and Atomic Structure Bohr's atomic model explains how electrons jumping between orbits in atoms cause emission and absorption line spectra and why each element has its own spectral signature. spectroscopy • atomic structure • absorption lines • spectral lines • emission lines
Early Theories of Atomic Structure J. J. Thomson and Ernest Rutherford pioneered studies of atomic structure, but their early models of the structure of the atom had serious flaws. atomic structure • structure of the atom • plum pudding model • ernest rutherford • jj thomson
Bohr's Model of the Atom The Bohr model of the atom was a major leap forward in our understanding of atomic structure and quantum mechanics, but it was not the final answer. bohr model of hydrogen atom • niels bohr • bohr atom • hydrogen atom • bohr atomic model |
