Transcript of Element Family Project: Carbon Family

Carbon Element Family The carbon family, in the p block, consists of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and quite unknown ununquadium (Uuq). Member Elements The carbon family elements contain atoms that have 4 electrons in their outer energy level. As you move down the periodic table in the carbon family the atomic radius increases while ionization energy decreases. In this family carbon is the only non-metal, silicon and germanium are mettalloids, and tin, lead, & ununquadium are all metals. The carbon family has only 2 electrons in the outermost p orbital... Chemical & Physical Properties lldadbdjkgbjfgkah ...their valence electron configuration ns^2 np^2. This family reacts in similar ratios with oxygen and other elements. They can form up to 4 bonds. Just as the atomic radii increases, the metallic character increases as you go down the group. The heavier elements of the group are more likely to keep their s electrons and can have oxidation numbers of +2 and +4. This group conforms well to general periodic trends. The atomic radii increases as you move down the group, and ionization energies decrease. Group 14 metalloids act as electrical semiconductors, even though silicon is mainly non-metallic. Their electrical conductivity can be affected in various degrees by doping (the addition of Group 13 or Group 15 elements in many different concentrations to the Group 14 solid matrix). Carbon makes up only 0.032% of earth's crust. Natural Occurrences Carbon in the form of diamonds have been found in meteorites. Carbon electrodes are widely used in electrical apparatus. The "lead" of the ordinary pencil is graphite mixed with clay. Silicon and silicate minerals are fundamental components of the Earth's crust. Silica (silicon dioxide) is the most common constituent of sand. Tin and lead, although with very low abundances in the crust, are as well common in everyday life... They occur in highly concentrated mineral deposits and are useful as metals and as alloys in many applications. Germanium ,on the other hand, forms few characteristic minerals and is most commonly found only in small concentrations in association with the mineral zinc blend and in coals. Tin can be used on the inside of aluminum cans. Uses "Carbon Family." About.com Chemistry. N.p., n.d. Web. 30 Sept. 2012
<http://chemistry.about.com/od/elementgroups/a/Carbon-Family.htm>. Work Cited What are the non-metals of the carbon family?
a) Carbon
b) Silicon and Tin
c) Sulfur and Magnesium
d) Germanium Review Carbon can be graphite or diamonds. Diamonds are used as accessories and sometimes tools. Silicon is used in transistors, computer chips, and solar cells. Si02 is the main ingredient in glass. Germanium is a huge semiconductor, which expands when it freezes. Lead is used in plumbing and is put in gasoline to prevent the engine from knocking. How many electrons does the carbon family have in it's outer most P orbital?
a) 4
b) 6
c) 2
d) 8 What is 'doping'?
a) Adding a chemical bond to the equation of metalloids.
b) Listing chemical properties between embers of the carbon family.
c) Adding Group 13 to Group 15 and subtracting different valence electrons.
d) The addition of Group 14 solid matrix. What is Silica?
a) An ion combing Silicon and Germanium.
b) Silicon Dioxide
c)The isotope form of Silicon
d) An element Carbon Family does not react with similar ratios of oxygen.
a) True
b) False a) Carbon a) 4 c) The addition of Group 14 solid matrix. b) Silicon Dioxide b) False "Carbon Group." Wikipedia. Wikimedia Foundation, 19 Sept. 2012.
