A Theory that Explains Electron Behavior the quantum-mechanical model explains the way electrons exist and behave in atoms helps us understand and predict the properties of atoms that are directly related to the behavior of the electrons electrons are incredibly small a single speck of dust has more electrons than the number of people who have ever lived on earth electron behavior determines much of the behavior of atoms directly observing electrons in the atom is impossible, the electron is so small that observing it changes its behavior QUANTUM MECHANICS EXPLAINS ALL CHEMICAL PHENOMENA!!!

    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.
