Periodic Table Families

Families on the Periodic TableElements on the periodic table can be

grouped into families based on their chemical properties.

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 METALSGroup 1 PropertiesType of element: MetalsValence Electrons: 1Reactivity: Very reactiveOther Shared Properties:

Soft; silver colored; shiny; low density

Examples: Soap, fertilizers, medicine

ALKALINE EARTH METALSGroup 2 PropertiesType of element: MetalsValence Electrons: 2Reactivity: 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 PropertiesGroups 3-12 Type of element: MetalsValence Electrons: 1 or

2Reactivity: Less reactive

than alkali-earth metalsOther 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 PropertiesType of element: 1

Metalloid & 4 metalsValence Electrons: 3Reactivity: ReactiveOther Shared

Properties: Solid at room temperature

Examples: Airplanes, siding, cans

CARBON FAMILY Group 14 PropertiesType of element: 1 non-

metal, 2 metalloids, 3 metals

Valence Electrons: 4Reactivity: VariesOther Shared Properties:

Solid at room temperatureExamples: Diamonds, tin cans

NITROGEN FAMILY Group 15 PropertiesType of element: 2 non-

metal, 2 metalloids, 1 metals

Valence Electrons: 5Reactivity: VariesOther Shared Properties:

All but Nitrogen are solid at room temperature

Examples: Air, fertilizers

OXYGEN FAMILY Group 16 PropertiesType of element: 3 non-

metal, 1 metalloids, 2 metals

Valence Electrons: 6Reactivity: ReactiveOther Shared Properties:

All but oxygen are solid at room temperature

Examples: Rust, some acids

Halogens Group 17 PropertiesType of element: Non-

metalsValence Electrons: 7Reactivity: Very ReactiveOther 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 PropertiesType of element: Non-

metalsValence Electrons: 8 ( 2

for helium)Reactivity: UnreactiveOther Shared Properties:

Colorless, odorless gases at room temperature.

Examples: Found in signs and balloons

Hydrogen Stands ApartHydrogen PropertiesType of element: Non-

metalsValence Electrons: 1Reactivity: ReactiveOther Shared Properties:

Colorless, odorless gas at room temperature; low density; reacts explosively with oxygen

Examples: Makes water with oxygen

Rare Earth MetalsSome are

RadioactiveThe rare

earths are silver, silvery-white, or gray metals.
