  8. The language of chemistry

  9. Chemical symbols are like the letters in the alphabet of chemistry Hill, J. and Petrucci, R. 1996. General Chemistry Instructor’s Edition.USA: Prentice-Hall, Inc.

  10. To describe compounds, chemical symbols are combined into chemical formulas, much as letters are combined to make words Elements present B2O3 two B atoms for every three O atoms Hill, J. and Petrucci, R. 1996. General Chemistry Instructor’s Edition.USA: Prentice-Hall, Inc.

  11. To describe compounds, chemical symbols are combined into chemical formulas, much as letters are combined to make words Elements present NH3 one N atom for every three H atoms Hill, J. and Petrucci, R. 1996. General Chemistry Instructor’s Edition.USA: Prentice-Hall, Inc.

  12. TEACHER:   Donald, what is the chemical formula for water? DONALD:     H I J K L M N O TEACHER:   What are you talking  about? DONALD:     Yesterday you said it's H to O  

  13. Naming compounds • ionic compounds • acids • covalent compounds

  14. Naming ionic compounds

  15. Ionic compounds = cation + anion • cation • positive ion (metal) • anion • negative ion (nonmetal) NaCl cation anion Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  16. Cations formed from metal atoms have the same name as the metal Na+ sodium ion Ca2+ calcium ion Al3+ aluminum ion Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  17. If a metal can form cations of differing charges,metal(charge in Roman numerals) Fe2+ iron(II) ion Cu+ copper(I) ion Fe3+ iron(III) ion Cu2+ copper(II) ion * Most of the metals that have variable charges are transition metals * If there is doubt whether a metal forms more than one type of cation, indicate the charge using Roman numerals Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  18. Polyatomic (many-atom) cations have special names NH4+ ammonium ion H3O+ hydronium ion Silberberg, M. 2010. Principles of General Chemistry. 2nd ed. New York: McGraw-Hill.

  19. For monoatomic (one-atom) anions, drop the ending of the name of the element and replace it with -ide N3- nitride ion O2- oxide ion F- fluoride ion Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  20. Polyatomic anions have special names Silberberg, M. 2010. Principles of General Chemistry. 2nd ed. New York: McGraw-Hill.

  21. For polyatomic anions containing oxygen (oxyanions) and a specific element, prefixes are used ClO4- perchlorate ClO3- chlorate ClO2- chlorite ClO-hypochlorite Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd. Silberberg, M. 2010. Principles of General Chemistry. 2nd ed. New York: McGraw-Hill.

  22. If H+ is added to an oxyanion, add the prefix hydrogen or dihydrogen (as appropriate) CO32- carbonate ion HCO3- hydrogen carbonate ion PO43- phosphate ion H2PO4- dihydrogen phosphate ion * Each H+ reduces the negative charge of the parent anion by one Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  23. To name an ionic compound, give the cation name followed by the anion name BaBr2 barium bromide CuCl2 copper(II) chloride K2SO4 potassium sulfate Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  24. To name an ionic compound, give the cation name followed by the anion name Al(NO3)3 aluminum nitrate* * For ionic compounds with more than one polyatomic ion group of the same type [i.e. three NO3- in Al(NO3)3], enclose the polyatomic ion’s formula in parenthesis before affixing the subscript ** When writing the chemical symbol of an ionic compound, start with the cation followed by the anion. If possible, reduce the subscripts to lowest terms Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  25. Naming acids

  26. An acid is a substance that yields H+ when dissolved in water HCl  H+ + Cl- H2SO4 2H+ + SO42- Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  27. If the anion that accompanies the H+ ends in –ide:1) add the prefix –hydro2) change –ideto –ic acid Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  28. If the anion that accompanies the H+ ends in –ate:1) change –ateto –ic acid Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  29. If the anion that accompanies the H+ ends in –ite:1) change –iteto –ous acid Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.

  30. Naming covalent compounds

  31. Covalent compounds = nonmetal + nonmetal NO nonmetal nonmetal

  32. Greek prefixes are used to indicate the number of atoms of each element Brown, , E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd. Chang, R. 2002. Chemistry 7th ed. Singapore: McGraw-Hill.

  33. The first element that appears is named as is, the second element is given an –ide ending P4S10tetraphosphorus decasulfide Cl2O dichlorine monoxide N2O4dinitrogen tetroxide NF3 nitrogen trifluoride * When the prefix ends in a or o and the name of the second element begins with a vowel, drop the a or o * The prefix mono is never used with the first element Brown, T., E. LeMay, and B. Bursten. 2000. Chemistry: The Central Science. 8th ed. Phils: Pearson Education Asia Pte. Ltd.
