Interpretations of Quantum Mechanics. Quantum mechanics is a physical theory developed in the 1920s to account for the behavior of matter on the atomic scale.

These subshells are given different letters to help chemists distinguish them from each other. The existence of nodes is analogous to the standing waves we discussed in the previous section. Emission spectrum for hydrogen showing purplish blue lines at 410 and 434 nm, a light blue line at 486 nm, and a red line at 656 nm.

That means the de broglie wavelength of our electron is such that it will often be encountering things with a similar size as its wavelengthfor instance, a neutron or atom. As such, the distance from the nucleus, , is the main factor affecting an electrons probability distribution. When that happens, the electron will be likely to demonstrate wavelike behavior! A major problem with bohrs model was that it treated electrons as particles that existed in precisely-defined orbits.

According to classical physics, the orientation of a dipole in an external magnetic field should determine the direction in which the beam gets deflected. Since knowing the energy of an electron is necessary for predicting the chemical reactivity of an atom, chemists generally accept that we can only approximate the location of the electron. Although it is more difficult to understand than the bohr model, it can be used to explain observations made on complex atoms. Image credit the p orbitals are shaped like dumbbells that are oriented along one of the axes.

    Louis de broglie proposed that all particles could be treated as matter waves with a wavelength erwin schrödinger proposed the quantum mechanical model of the atom, which treats electrons as matter waves. Electrons occupying higher-energy orbitals have greater probabilities of being found farther from the nucleus. Each orbital has a set of four quantum numbers that come out of schrödingers equation.

    If chemists ever need a larger value, they can create subshell numbers and letters. For example, if the n value is 3, three values are allowed for. A model is useful because it helps you understand whats observed in nature.

    The four quantum numbers are as follows , the principal quantum number, is the major factor in determining the energy of an orbital. Therefore, as we learn more about the electrons position, we know less about its energy, and vice versa. Some of this behavior is so counterintuitive that we can only talk about it with symbols and metaphorslike in poetry. Based on de broglies idea that particles could exhibit wavelike behavior, austrian physicist erwin schrödinger theorized that the behavior of electrons within atoms could be explained by treating them mathematically as matter waves.
