By this point, we are past By the current periodic table so we can stop. so 7i? 38 Why are d and f orbitals always in lower energy levels? • d and f orbitals require LARGE amounts of energy • It’s better (lower in energy) to skip a sublevel that requires a large amount of energy (d and f orbtials) for one in a higher level but lower energy This is the reason for the diagonal rule! BE SURE TO FOLLOW THE ARROWS IN ORDER! How many electrons can be in a sublevel? 39 Remember: A maximum of two electrons can Remember: be placed in an orbital. be s orbitals p orbitals d orbitals f orbitals Number of orbitals Number of Number electrons electrons Electron Configurations 40 A list of all the electrons in an atom (or ion) • Must go in order (Aufbau principle) • 2 electrons per orbital, maximum • We need electron configurations so that we can determine the number of electrons in the outermost energy level. These are called valence electrons. • The number of valence electrons determines how many and what this atom (or ion) can bond to in order to make a mole...
