Each family has a specific name to differentiate it from the other families in the periodic table. Elements in each family react differently with other elements. ALKALI METALS Group 1 Properties Type of element: Metals Valence Electrons: 1 Reactivity: Very reactive Other Shared Properties: Soft; silver colored; shiny; low density Examples: Soap, fertilizers, medicine ALKALINE EARTH METALS Group 2 Properties Type of element: Metals Valence Electrons: 2 Reactivity: Very reactive, but less reactive than alkali metals Other Shared Properties: Silver colored; more dense than Alkali metals Examples: Cement, plastics, chalk TRANSITION METALS Group Properties Groups 3-12 Type of element: Metals Valence Electrons: 1 or 2 Reactivity: Less reactive than alkali-earth metals Other Shared Properties: Shiny; good conductors of thermal energy and electric current; Higher densities and melting points (except Mercury) than elements in Group 1 or 2 Examples: Thermometers, jewelry BORON FAMILY Group 13 Properties Type of element: 1 Metalloid & 4 metals Valence Electrons: 3 Reactivity: Reactive Other Shared Properties: Solid at room temperature Examples: Airplanes, siding, cans CARBON FAMILY Group 14 Properties Type of element: 1 non-metal, 2 metalloids, 3 metals Valence Electrons: 4 Reactivity: Varies Other Shared Properties: Solid at room temperature Examples: Diamonds, tin cans NITROGEN FAMILY Group 15 Properties Type of element: 2 non-metal, 2 metalloids, 1 metals Valence Electrons: 5 Reactivity: Varies Other Shared Properties: All but Nitrogen are solid at room temperature Examples: Air, fertilizers OXYGEN FAMILY Group 16 Properties Type of element: 3 non-metal, 1 metalloids, 2 metals Valence Electrons: 6 Reactivity: Reactive Other Shared Properties: All but oxygen are solid at room temperature Examples: Rust, some acids Halogens Group 17 Properties Type of element: Non-metals Valence Electrons: 7 Reactivity: Very Reactive Other Shared Properties: Poor conductors of electric current; react violently with alkali metals to form salts, never found uncombined in nature. Examples: Toothpaste, Water treatment, disinfectatants Noble Gases Group 18 Properties Type of element: Non-metals Valence Electrons: 8 ( 2 for helium) Reactivity: Unreactive Other Shared Properties: Colorless, odorless gases at room temperature. Examples: Found in signs and balloons Hydrogen Stands Apart Hydrogen Properties Type of element: Non-metals Valence Electrons: 1 Reactivity: Reactive Other Shared Properties: Colorless, odorless gas at room temperature; low density; reacts explosively with oxygen Examples: Makes water with oxygen Rare Earth Metals Some are Radioactive The rare earths are silver, silverywhite, or gray metals. Conduct electricity Indentify if the element is a metal, metalloid or non-metal.
