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. **// // One flaw in Rutherford's model is that it has charges that are accelerating. The charges are accelerating because the electrons are always changing direction as they move around their orbits. One flaw in Rutherford's model is that it has charges that are accelerating. The charges are accelerating because the electrons are always changing direction as they move around their orbits. // //** Summarize Bohr’s model of the atom. Compare and contrast his model to Rutherford’s model. What new knowledge did we gain? What was wrong with Rutherford’s model? Did any of Rutherford’s ideas continue to be valid? **// // Bohr's model of the atom was based on Rutherford's theory, but in Rutherford's model it showed that the nucleus was positively charged with negative electrons orbiting around it. We learned in Bohr's theory that the outer orbits could hold more electrons than the inner ones and that the electron's orbit the nucleus. In Rutherford's model he couldn't figure out how to change the way the electrons orbited arounf the nucleus but later Bohr figured out that the that electrons can only travel in certain large orbits. // //** Summarize Bohr’s concept of electrons absorbing and emitting energy. **// // Electrons can absorb and emit energy by taking the wavelength of the emitted energy and finding the difference between the two orbits. // // **What are atomic line spectra? Where do they come from? Include visuals of line spectra of at least two different elements.** // Line spectra are when a matter is heated its gives off light. When normal white light, such as that from sun, is passed through a prism, the light separates into a continuous spectrum of colors.
