recognized oxygen as an element, and coined its name which comes from a Greek word that means acid-former.
best known for his research in electromagnetic radiation, which unites the sciences of electricity, magnetism and optics.
Studied "canal rays" and found they were associated with the proton H + .
was a physicist and chemist famous for her pioneering research on radioactivity
He discovered the nucleus and the gold foil experience.
published the results of his measurements of the wavelengths of the X-ray spectral lines of a number of elements which showed that the ordering of the wavelengths of the X-ray emissions of the elements coincided with the ordering of the elements by atomic number
Bohr said that electrons traveled in circular orbits around the nucleus, yes their is a difference between an orbit and an orbital.
Viewed electrons as continuous clouds and introduced "wave mechanics" as a mathematical model of the atom.
Using alpha particles discovered a neutral atomic particle with a mass close to a proton. Thus was discovered the neutron.
Described atoms by means of formula connected to the frequencies of spectral lines. Proposed Principle of Indeterminancy - you can not know both the position and velocity of a particle.
