Bohr's Model of the Atom
slide one
- He added that the electrons are attached to the rings.
- They occupy regions of the rings determined by the energies.
- The atom includes a small,positively charged nucleus.
slide two
slide 3
- He based his theory on Ernest Rutherford's experiment.
- The experiment directed a narrow beam of alpha particles at a sheet of gold foil surrounded by a fluorescent screen. With this, they concluded that it didn't need any deflection because the atom had empty spaces.
slide 4
- According to Rutherford's experiment,the alpha particles should have passed easily through the gold foil, with a little bit of deflection due to the positive charges that were thought to be spread out in the gold atoms.
slide 5
- Niel Henrik David Bohr was a Danish physicist who made contributions to understand the atomic structure. He received the Nobal Prize in physics in 1922. He collaborated with many of the top physicists. He was in the British team of physicists working on the Manhattan project. He married Margrethe Norlund in 1912 and on of their sons, Aage Bohr, was also a physicist and also recieved the Nobal prize in 1975.
