PPT-Electron Population

What we know Bohr model But Atoms move Only predict where an electron may be Electrons have energy The amount of energy tells us how far apart it is from the nucleus Orbitals Is a space around a nucleus in which an electron is likely to be found.

Up until now, when you have met waves and particles, you will have treated them as separate entities. However, you will soon find that particles exhibit wave like behaviour and vice versa! This experiment will illustrate this. . cont’d. Ms. McGrath . Chemistry 11. Aufbau. . principle. States that in going from a hydrogen atom to a larger atom, you add protons to the nucleus and electrons to orbitals . You start at the orbitals having the lowest energy level and fill them, in order of increasing energy, until you run out of electrons. Electron Shells. Periods on the periodic table are similar because they have the same number of electron shells.. Within these shells there are layers called sublevels', a shell can have between 1 and 4 sublevels.. the development of quantum theory early in the twentieth century and remains at the frontier of physics today There are several inconsistent Modern quantum theory reinforces Bohrs conclusion that what The aims of this course are:. ● . to introduce the principles of scanning electron microscopy. ● . to describe the components of the microscope and explain how they work. ● . to highlight some of the problems which can arise during imaging. Three rules:. electrons fill orbitals starting with lowest n and moving upwards;. The order is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d etc.. Orbital Diagram.
