Do Now Based on what we learned yesterday, what
does the structure of the periodic table allow us to predict about an element?
The periodic table allows us to predict chemical and physical properties of an element.

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
Customize Your Periodic TableThis is YOUR periodic table to use throughout the year. Make
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
