Periodic Table Groups – columns (a.k.a. “Families”) Numbered 1 – 18 OR IA – VIIIA/IIIB – IIB Periods – rows Numbered 1 - 7

COLOR CODE YOUR PERIODIC TABLE!

Properties of Common Groups Alkali Metals (Group 1A or 1) the most reactive metal family must be stored under oil react with water violently! Alkaline Earth Metals (Group 2A or 2) except for Be(OH)2, the metal hydroxides formed by this group create basic (pH > 7) solutions in water pastes of these used in batteries

Properties of Common Groups Chalcogen family (Group 6A or 16) many found combined with metal ores Halogens (Group 7A or 17) known as the “salt-formers” because they form ionic compounds with metals used in modern lighting

Properties of Common Groups Noble gases (Group 8A or 18) known for their disinterest in other elements once thought to never react neon used to make bright RED signs Transition Metals (Group 8A or 18) fill the d orbitals ions are very colorful: nickel = green copper = blue
