Niels+Bohr

Niels Bohr [] [|www.kentchemistry.com/links/AtomicStructure/Bohr.htm] Based on the two videos, explain the major flaws of Rutherford’s model of the atom.

Answer: The major flaw of Ruthford's model was one of his theories stated that electrons move randomly in the space around the nucleus. Bohr corrected Ruthford, by stating electrons move in an organized path around the nucleus. In amore specific way, the electons orbits around the atom nucleus in an fixed accurate distance.

Summarize Bohr’s model of the atom.

Answer: Nucleus surronded by a large amount of space. Electrons orbit in an organized path around the nucleus from a fixed distance, like planets orbits around the sun. Bohr's model also fixed it's attention more on the electrons. Bohr states that each electrons moved with a constant speed in a specific distance from the nucleus and each electron has an specific amount of energy. He also state that if an atom loses or gain energy, the electron gain or lose as well.

Compare and contrast his model to Rutherford’s model.

Answer: Both Bohr and Ruthford agreed that nucleus was surronded by a large amount of space. The only differences between the two models is that, Ruthford states that the electrons move randomly in the space surronding the nucleus. Bohr corrected ruthford, by saying: the electron orbits in a spicific path in the empty space around the nucleus.

What new knowledge did we gain?

Answer: For because electrons move between accurate distance and levels. We now know electrons gain or lose energy when they move.

What was wrong with Rutherford’s model?

Answer: Ruthford's model did not focus on the electrons.

Did any of Rutherford’s ideas continue to be valid?

Answer: Ruthford's theory about large space around the nucleus, still stands today.

Summarize Bohr’s concept of electrons absorbing and emitting energy.

Answer: Electrons gain energy by asboring Protons

Bohr's visual model of the atom:

In 1913 Bohr introduced a theory about the structure of the atom based on an earlier theory of Rutherford's.
