Explore Periodic Table element classifications: Metals, Nonmetals, Metalloids, and key families!

Parts of the Periodic Table Element Classification Vertical COLUMNS on the Periodic Table Family or Group Horizontal ROWS on the Periodic Table Period MOST of the ELEMENTS of the Periodic Table are classified as: Metals Element classification that makes a ZIG ZAG line on the right side of the Periodic Table and has properties of BOTH metals and nonmetals. Metalloids Element classification with POOR CONDUCTORS Nonmetals Key Periodic Families VERY ACTIVE, soft, silver, low density Metals that react with oxygen & water. Alkali Metals These Elements like to form SALTS with Group 1 Elements. Halogens LEAST ACTIVE Group of Elements. Noble Gases Place these Elements in their Proper Families. Alkali Metals Na Li K Halogen Cl F I Noble Gases He Ne Xe Rn Element Identification Match (Alkaline Earth Metals - Carbon Group) A Semiconductor used in computer chips Silicon Makes up Diamonds & Pencil Graphite Carbon Found in Pyrex Glassware & Bulletproof Armor Boron Element Identification Match (Nitrogen Group - Noble Gases) Radioactive Result of Uranium Decay (People should test their basements for this colorless, odorless gas.) Radon Makes up 20% of Earth's Atmosphere Oxygen Noble Gas known for its Glows when Electrified Neon Nonflammable Noble Gas used in Blimps Helium
