Unformatted text preview: e d4, one of the closest s electrons will go into the d, this time making it d 10 instead of d9. For example: Au would be [Xe] 6s2 4f14 5d9, but since this ends exactly with a d9 it is an exception to the rule. Thus, Au should be [Xe] 6s1 4f14 5d10. Procedure: Same as before! Find the closest s orbital. Steal one electron from it, and add it to the d. (HONORS only) 60 Try These! • Write the shorthand notation for: Cu W Au Orbital Diagrams • Graphical representation of an electron configuration • One arrow represents one electron • Shows spin and which orbital within a sublevel • Same rules as before (Aufbau principle, d4 and d9 exceptions, two electrons in each orbital, etc. etc.) 61 Orbital Diagrams • One additional rule: Hund’s Rule – In orbitals of EQUAL ENERGY (p, d, and f), place one electron in each orbital before making any pairs – All single electrons must spin the same way • I nickname this rule the “Monopoly Rule” • In Monopoly, you have to build houses EVENLY. You can not put 2 houses on a property until all the properties have at least 1 house. 62 Lithium Lithium 63 Group 1A Atomic number = 3 1s22s1 ---> 3 total electrons 3p 3s 2p 2s 1s 64 Carbon Carbon 3p 3s 2p 2s 1...
