2Metals Shiny Conduct electricity Magnetic React with acid to produce hydrogen gas.Malleable and ductileLocated to the left of the “stair step line” on the periodic table, except hydrogen.
3Nonmetals Not shiny Do not conduct electricity Not magnetic Do not react with acidLocated to the right of the “stair step” line, and also hydrogen
4Metalloids or semi-metals Have both metallic and nonmetallic propertiesPoor conductors of electricityNot magneticElements that touch the “stair step” line, except aluminum which is a metal.B, Si, Ge, As, Sb, Te, Po, At
6OrganizationThe periodic table is organized by increasing atomic number.It is divided into groups and periodsThe rows are called periodsThe columns are called groups or families.Properties repeat across rows and elements in the same group also have similar properties.
7Groups of elementsThere are 7 groups on the periodic table that you will be responsible for knowing.Group 1: alkali metalsGroup 2: alkaline earth metalsGroups 3-12: transition metalsGroup 17: halogensGroup 18: noble gasesFor the bottom 2 rowsRow 1: lanthanidesRow 2: actinides
