NOVA: Hunting the ElementsPart 1: Basic ChemistryBlank Periodic TableFill in the parts of this periodic table covered by the documentary.Noble Metals, Noble Gases, Elements of Life (CHNOPS), Rare Earth Elements, Radioactive Elements, Synthetic ElementsGold - Au Write the number of subatomic particles in gold:Protons: Neutrons: Electrons: Give one property of gold.How much gold is in one ton of the mined rock?How much is each truckload of ore worth, once the gold is extracted?What determines how reactive an element is?Write and color code the noble metals on the blank periodic table.Why is gold so heavy?Copper - Cu Write the number of subatomic particles in copper:Protons:Neutrons:Electrons:List three uses of copper.Give one property of copper.Tin - SnWhat alloy does tin make when mixed with copper?How are atoms arranged in pure metals?Why isn’t pure copper used for bells instead of bronze?Electron MicroscopeHow much would you have to zoom in on a map of the United States to replicate the power of an electron microscope?Why is the microscope wrapped in acoustic blankets?What part of the atom is actually visible under the microscope?What do protons determine about an element?What is the number of protons called?Label the atomic number, symbol, and atomic mass of calcium below: Give an example of a real-life object made from each of the following elements:Calcium – Bismuth –Bromine –What is a family of elements?Where did the noble gases get their name?What do electrons determine?How many electrons can fill each of the orbital levels in the diagram below? Chlorine - ClGive the number of atomic particles in chlorine:Protons – Neutrons – Electrons – Chlorine wants to ( take / give away ) one electron, becoming an ( ion / isotope ).Why do alkali metals and halogens react so strongly with other elements?What do sodium and chlorine make when combined? Compare the properties of each of the following:Sodium (Na)Chlorine (Cl)Sodium Chloride (NaCl)State of MatterReactive or StablePractical UseOxygen - O What is ANFO?What do each of the spikes on the ion chromatograph represent?This is the chemical reaction of the ANFO explosion. Explain what happens during this reaction to release so much heat energy.C + NH4NO3 – H2O + N2 + O2 Write the chemical equation for the burning candle.Write the chemical equation for the formation of pare the speed and explosive force of gunpowder, emulsion-gel, and C4. Which is the fastest? Explain why.NOVA: Hunting the ElementsPart 2: Chemistry of Life, Rare Earth Elements, and RadioactivityElements of Life List the six most common elements of life, a common object they are found in, and an important property.Element SymbolElement NameCommon ObjectImportant PropertyCHNOPS What can happen when excessive trace elements are lost from the body?Describe a body function or part that utilizes each of these trace elements:Calcium – Iron – Potassium – Zinc – Magnesium – Sodium – What three conditions did the earliest bacteria need for energy production?What do cyanobacteria use for energy production? What do they release as waste?In the core sample collected from Yellowstone, which layer is the cyanobacteria?Origin of the ElementsWhat is the origin of hydrogen, the smallest element?Describe the process of fusion and how it produces helium.What happens when a star runs low on hydrogen fuel?What is created in supernova explosion?Silicon and Glass What elements is sand made of?What is added to Gorilla Glass to make it stronger than normal glass?Rare Earth Elements Where do most of the rare earth elements come from?How are the fifteen rare earth elements chemically similar?What elements are rare earth magnets usually made of?Why are rare earth elements in such short supply? How do sharks react to rare earth metals?Describe the following parts of the lemon shark experiment:Independent Variable –Dependent Variable –Experimental Group –Control Group -Carbon Isotopes What is the difference between the compositions of these carbon isotopes?ProtonsElectronsNeutronsCarbon-12Carbon-13Carbon-14What happens to Carbon-14 over time?Define radioactive half-life:Based on carbon dating, how long ago did the tree die?Nuclear RadiationGive the number of subatomic particles in uranium:Protons –Neutrons –ElectronsHow is the mousetrap simulation similar to a fission chain reaction?What element was used as fuel for the “Little Boy” bomb?What element was used as fuel for the “Fat Man” bomb? ................
