chemistry chapter 9 study guide Study online at https://quizlet.com/_ce1lon 1. anion: A negatively charged ion nonmetal located to the right of the stair case 2. cation: A positively charged ion metal located to the left of the stair case 3. monotomic ion: an ion formed from only one atom 4. polyatomic ion: groups of atoms that stay together and have an overall charge usually end in -ate or -ite 5. ionic compound: A compound that consists of positive and negative ions 6. binary compound: a compound composed of two elements Formula- First write the symbol of the cation and then the anion-> then add sub- scripts as needed to balance the charges 7. acids: a group of ionic compounds that contain at least one hydrogen atom and produces hydrogen ion when dissolved in water FORMULA WILL START WITH H Anion determines the name of an acid formula 8. base: anything that ends in an OH- same naming rules as other ionic compounds 9. ions: atoms with a charge 10. naming monatomic anions: the ending changes to ide ex: O2: oxide ion 11. Know what ion elements in each group on the periodic table form (what's the charge): group 1: 1+ group 2: 2+ group 13: 3+ group 14: 4+ or 4- group 15: 3- group 16: 2- group 17: 1- 12. Be able to determine the charge of an ion in a compound when given the formula of the compound: 13. Ionic compound vs molecular compound (composition, methods of nam- ing, etc): 14. metals location: left of staircase 15. nonmetals location: right of staircase 16. why do atoms have a charge?: because they form when electrons are given or taken away 1/2  chemistry chapter 9 study guide Study online at https://quizlet.com/_ce1lon 17. How do you indicate an ion of a transition element that has more than one common ionic charge?: by using roman numerals the roman numeral must have the same value as the charge of the ion ex: Fe2+ = iron(II) FeCl2 = iron(II) chloride 18. How is the number of each atom of an element present in a binary molec- ular compound indicated when naming the compound?: with prefixes 19. What does an -ite or -ate ending on the name of a compound usually indicate: it is a polyatomic ion 20. what are the common transition metals that have more than one ionic charge?: 21. what does an -ite or -ate ending in a polyatomic ion mean?: -ITE: has less oxygens -ATE: has more oxygens 22. make sure you can write the formulas of compounds when given the names and can name the compounds when given the formulas: 23. when given a pair of ions, be able to write the correct formula and then name the compound formed by combining the two ions: 24. the ions in a binary ionic compound are written in what order? (what comes first, the cation or the anion?: cation (the metal) is written first 25. metric prefixes: 1: mono 2: di 3: tri 4: tetra 5: penta 6: hexa 7: hepta 8: octa 9: nona 10: deca 26. know how to name or write the formulas for acids and bases: 27. Be able to compare binary compounds and molecular compounds and describe how to write each: 28. honors: know common polyatomic ions: 2/2
