Name ________________________________________ HP Chemistry Summer Assignment Fill in the blanks given above with the names of the elements and the symbols represented. Be able to give either the symbol or its name from memory for the elements listed below on the first day of class. You will always be provided with a periodic table like the one attached to this packet. To complete this assignment, you will need to find a periodic table that has both the symbol and name listed. Hydrogen _______ Beryllium _______ Arsenic _______ Fluorine _______ Lithium _______ Titanium _______ Oxygen _______ Argon _______ Neon _______ Iodine _______ Magnesium _______ Strontium _______ Phosphorus _______ Platinum _______ Bismuth _______ Sulfur _______ Cobalt _______ Manganese _______ Carbon _______ Krypton _______ Bromine _______ Boron _______ Calcium _______ Zinc _______ Nitrogen _______ Aluminum _______ Barium _______ Silicon _______ Cadmium _______ Chromium _______ Chlorine _______ Nickel _______ Helium _______ Selenium _______ Some symbols are derived from non-­‐English words (Latin, Greek, or German). Iron _______ Copper _______ Sodium _______ Potassium _______ Silver _______ Mercury _______ Tin _______ Antimony _______ Lead _______ Gold _______ Tungsten _______ When naming chemical compounds, it is important to know the possible charge/oxidation number for the elements in the compound. Many ion charges can be predicted by looking at their position on the periodic table. The ions listed below should be known by the first day of school. You will always be provided a periodic table. 1+ Alkali Metals 2+ Alkaline Earth Metals Oxidation States of Representative Cations and Anions Hydrogen, H+ 3+ Boron Family Lithium, Li+ 3-­‐ Nitrogen Family Sodium, Na+ Potassium, K+ 2-­‐ Oxygen Family 2+
Beryllium, Be Magnesium, Mg2+ 1-­‐ Halogens Calcium, Ca2+ Strontium, Sr2+ Barium, Ba2+ Aluminum, Al3+ Nitride, N3-­‐ Phosphide, P3-­‐ Oxide, O2-­‐ Sulfide, S2-­‐ Fluoride, F-­‐ Chloride, Cl-­‐ Bromide, Br-­‐ Iodide I-­‐ Transition metals/other metals often have more than one possible charge/oxidation number. Notice these ions HAVE a Roman numeral in their name. (There are many more than the ones listed below): Cations with Variable Oxidation Numbers 1+, 2+ Copper (I), Cu+ Copper (II), Cu2+ Mercury (I), Hg22+ Mercury (II), Hg2+ 2+, 3+ Chromium (II), Cr2+ Chromium (III), Cr3+ Cobalt (II), Co2+ Cobalt (III), Co3+ Iron (II), Fe2+ Iron (III), Fe3+ Nickel (II) Ni2+ Nickel (III) Ni3+ Manganese(II), Mn2+ Manganese (III), Mn3+ 2+, 4+ Lead (II), Pb2+ Lead (IV), Pb4+ Tin (II), Sn2+ Tin(IV), Sn4+ Some transition metals have only one possible charge/oxidation number. Notice these ions do NOT have a Roman numeral in their name. Transition Metals with Only One Oxidation State 1+ Silver, Ag+ 2+ Cadmium, Cd2+ Zinc, Zn2+ Polyatomic ions describe a group of atoms that behave as a single ion. There is no simply way to learn these. The following list includes the most polyatomic ions needed for HP Chemistry. They MUST be MEMORIZED by August 19th, 2013. Common Polyatomic Ions Bromine Bromate, BrO3-­‐ Carbon Acetate, C2H3O2-­‐ Carbonate, CO32-­‐ Hydrogen carbonate/ Bicarbonate, HCO3-­‐ Oxalate, C2O42-­‐ Chlorine Perchlorate, ClO4-­‐ Chlorate, ClO3-­‐ Chlorite, ClO2-­‐ Hypochlorite, ClO-­‐ Chromium Chromate, CrO42-­‐ Dichromate, Cr2O72-­‐ Hydrogen Hydronium, H3O+ Iodine Iodate, IO3-­‐ Manganese Permanganate, MnO4-­‐ Nitrogen Ammonium, NH4+ Cyanide, CN-­‐ Thiocyanate, SCN-­‐ Nitrate, NO3-­‐ Nitrite, NO2-­‐ Oxygen Peroxide, O22-­‐ Hydroxide, OH-­‐ Phosphorus Phosphate, PO43-­‐ Hydrogen phosphate/biphosphate, HPO42-­‐ Dihydrogen phosphate, H2PO4-­‐ Sulfur Sulfate, SO42-­‐ Sulfite, SO32-­‐ Hydrogen sulfate/bisulfate, HSO4-­‐ Hydrogen sulfite/bisulfite, HSO3-­‐ Silicon Silicate, SiO32-­‐
