MetalsShinySolid at room temperatureConduct heat and electricityMalleable and ductile

Alkali MetalsGroup 1 (except hydrogen)Extremely reactive – found in compounds

with other elementsExtremely soft (can cut with a knife)Example: sodium (Na) is found in table

salt

Alkaline Earth Metals

Group 2 elementsHighly reactiveSofter than most metals except the alkalisExample: Calcium (Ca) is used in muscle

contractions

Transition MetalsGroups 3-12Create color in many compoundsCan have magnetic propertiesExample: Iron (Fe) is used in construction

because it is strong

Inner Transition Metals

Two sets at the bottom of the table

Lanthanide Series (top)

Actinide Series (bottom)Example: Elements in the Lanthanide

series are used as phosphors (emit light when hit with electrons)

Non-MetalsTypically gases or dull solidsPoor conductors of electricity and heatVery important in living organisms

HalogensGroup 17Highly reactive – bad for living creatures in

high dosesExamples: chlorine in swimming pools

Noble GasesGroup 18Extremely unreactiveColorless, odorlessExample: Neon gas is used to light up

neon signs

MetalloidsBorder between metals and non-metalsHave physical and chemical properties of

both metals and non-metalsExamples: Silicon is used in both

computers and prosthetics

it pretty and make it your own!

Select a color and color all the metalloids: B, Si, Ge, As, Sb, Te, Po, At

Select a second color and color all the non-metals All the noble gases All the halogens (except for astatine) H, C, N, O, P, S, Se

Select a third color and color all the metals (remember – hydrogen is NOT a metal)

Label the following groups: Alkali metals Alkaline earth metals Halogens Noble Gases Lanthanide Series Actinide Series
