Things that need to be in your homework notebook when it’s turned in on test day… ___ /10 BAT answers on another sheet ___ / 5 Ionic Bingo sheet (24 correct compounds) ___ / 5 Lewis Dot Introduction worksheet ___ / 5 Here’s a Bit of a Challenge worksheet ___ / 5 Naming & Drawing Ionic Compounds wkst ___ / 5 Today we build worksheet ___ / 5 Ionic Naming Worksheet ___ / 5 Outlining Guide for 9.1 & 9.2 worksheet ___ / 5 Formula & name & bonding of CaCl2, Al2O3, barium nitride, lithium bromide ___ / 5 Names & formulas of (with work) CuO, Cu2O, MnS2, Mn2S7, PbCl4, PbCl2, zinc bromide, silver sulfide, titanium (II) oxide, titanium (III) chloride, titanium (IV) sulfide ___ / 5 Polyatomic Ion Naming wkst For the test, you need to Be Able To… …determine the number of protons, neutrons, and electrons in an atom or (especially) an ion… 1. Make a chart listing the symbol, charge, atomic number, mass number, protons, neutrons, and electrons for each of the following atoms or ions: most common ion of magnesium-24 neutral atom of uranium-238 nitride ion with seven neutrons halogen with thirty-five protons, a charge of –1, and 45 neutrons …identify a compound as ionic or molecular… 2. Make a chart with two columns. Label the first “ionic” and the second “molecular.” Place each of these compounds under the correct column. sodium phosphate copper (II) chloride (NH4)2CO3 BaO P 4H 8 AgNO3 nitrogen trifluoride C5H10 S 2O 3 FrF H 2O CaCl2 Cr(OH)6 FeCO3 LiCN Mg3(PO4)2 N 2O 4 XeF6 …name a compound if the formula is given or write a formula from the name of a compound… 3. For the eleven ionic compounds in question two, write the name or formula for each one – the opposite of whichever is listed. 4. Write the formula of the compound formed between barium’s most common ion and sulfur’s most common ion. Then write the formula of the compound formed between manganese’s (III) ion and oxygen’s most common ion. 5. Write the formula for each of these three compounds…calcium phosphate, calcium phosphide, and calcium phosphite. 6. Typically, chemistry teachers explain that an ionic compound contains a metal and a nonmetal. This is not entirely true. Ionic compounds usually are made of a metal with a nonmetal, but they are always made of a positive ion and a negative ion. Write the correct names and formulas for three ionic compounds that do not contain a single metal atom. (Hint: Check page 257’s chart for help – replace the metal in an ionic compound with something else.) 7. In a couple of complete sentences, explain why it is easier and more systematic for chemists to use the Stock (Roman numeral) system instead of the older, classical name. Feel free to use pages 254 & 255 as reference. …name your favorite elements… 8. Name your favorite element of each of these groups…halogens…element that makes a cation…elements that forms an ion with a negative three charge…metalloid…transition metal… metal with an atomic mass greater than 42.5 amu…transition metal with an atomic number that is a multiple of seven. …explain why some elements bond ionically (sp?) & others bond covalently… 9. Explain what happens when an atom of chlorine is placed with atoms of sodium. Use a few complete sentences and include all of the following words: electronegativity, protons, electrons, ionization energy, ion, octet rule, energy level, full. 10. Explain why a compound of chlorine and oxygen will bond covalently. Use a few complete sentences and include all of the following words: electronegativity, protons, electrons, ionization energy, ion, octet rule, energy level, full. …show the formation of an ionic compound using Lewis dot structures… 11. Show the formation of the compound Al2O3. 12. Show the formation of the compound barium chloride. …again, a warning that anything that has appeared on a previous test is fair game for this test…especially what went poorly on the last quiz (atomic mass vs mass number, periodic table history, special groups on the table, and the periodic law) …just warning you, you’ll have a lot of questions on the test about how to name compounds or how to write the formulas of compounds…I didn’t put a ton of those on this sheet because you’ve had a bunch of naming worksheets about it…
