orbits cold be subdivided into sub-orbits or sublevels * De Broglie - Proposed that matter, in particular electrons, may have wave-like properties * Schrödinger - used the concept of mater waves to determine the mathematical probability of finding electrons around the nucleus * Heisenberg - Proposed that the position and momentum of an electron cannot be determined with any degree of accuracy at the same time What did Rutherford observe during the gold foil experiment that allowed him to conclude atoms contained a central nucleus? - He shot alpha particles at the gold foil - The majority of them went through while others were deflected back - Because common charges repel, there was a dense centre of positively charged protons at the centre of the nucleus What was the flaw with Rutherford’s proposed nuclear model - When anything accelerates, it loses energy and should move closer to the nucleus - It would cause the atom to collapse which is not happen in nature What is meant by electrons are quantized - Electrons emit different levels of quantum Explain how the photoelectric effect illustrates the quantized nature of electrons - Photoelectric effect says that if you shine a light on a metal surface, it will release electrons - The amount of electrons that are removed is dependent on the wavelength of the light - If the wavelength of light is lower in energy, it will not have enough energy to remove the electron from its ground state How did Bohr explain specific wavelengths of light in bright-line spectrum by atoms?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
