Family 1Alkali metals --- Valence # 1, ox. # --- form bonds easily --- Never found as free element --- found in many products

Family 2 Alkaline earth metals ---never found free in nature ---valence # of ________Ox. # _____ ---magnesium used to make light, strong metals

--- calcium -- bones, limestone, marble,tub rings

most abundant Grp 23.6% of the

crust(3rd most abundant metal after___________ and _________

--- strontium-90 product of fallout -- Why are scientists concerned about its appearance in milk production?

Go to webelements?

Click on Calcium.

At the bottom left hand corner, click on “electron configuration”

Does its electron configuration make sense?

Click on the next element to the right of Ca which is Sc. Does this make sense?

Click on the next element to the right of Sc which is Ti. Does this make sense?

Click on the next element to the right of Ti which is V. Does this make sense?

QuickTime™ and aTIFF (Uncompressed) decompressor

are needed to see this picture.

Why does this make sense considering it is a transition metal? What is the valence # for most transition metals?

Transition metals (3-12) --- properties similar to one another, but they are different from the properties of any other family. --- most lose 1 or 2 valence electrons

--- they can lose an electron from the next to outermost energy level --- they can also share electrons with other elements.

Family 13 Boron Family --- 3 valence

What does it look like?

Family 13all have _____ valence electronsboron used to make heat-resistant glass Does this make sense?

aluminum -- 1) most abundant metal in the crust (3rd overall. Was displayed near the crown jewels in 1827 b/c price was $500/lb 2) often found combined with oxygen in the ore bauxite 3)does not corrode (resistant to oxidation

Was aluminum as reactive as Magnesium?

Family 14 --Carbon Family

--Valence # of ________

--Carbon -- only able to form_________

Unique because of the vast number of forms. Crude oil used to make plastics.

--found free in nature--diamonds, graphite, buckmisterfullerene (C60)

--Si and Ge are used as ___________

--Si ___most abundant at 27%

Nitrogen Fam #15

Ox # =

--N -- odorless, colorless, inert

--P --active nonmetal -- white spontaneous combustion, red not spon.

Family 17

The halogens

Ox # --??

They are never found ________.

Family 18--Noble Gases

They are inert. Why?

Rare Earth Elements

Why are these elements rare?

Lanthanoid series

High luster and conductivity

Actinoid series

Why are they called Transuranium elements?

Why are they radioactive?

What are 2 of the radioactive particles a radioactive element like Polonium-210 could release?

What are 2 of the radioactive particles a radioactive element like Polonium-210 could release?

Alpha particle -- He nucleus -- 2 + , 2 neutrons

Why does the atom transmutate when it releases an alpha particle?

Beta particle -- e-

An element absorbs a neutron, this changes to a proton and ejects a high energy e- (beta particle)

Gamma rays -- pure energy
