  1. Ionic BondingNaming Salts

  2. Ionic Bonds An ionic bond is a very strong attraction between a positive cation and a negative anion. Na - + Cl

  3. Crystal Lattice Structure The ions organize themselves in a pattern of alternating charge called a crystal lattice. The strong attractions cause ionic compounds (salts) to have high melting and boiling points.

  4. Balancing Charges For most compounds to be stable, they must have a neutral overall charge. S2- Mg2+ If necessary, add ions to balance charges. Mg2+ F1- F1-

  5. Chemical Formulas Once bound as a salt, write the elements with the cation then anion symbols and no spaces or charges. Mg2+ + S2- → MgS

  6. Coefficients and Subscripts If a compound requires more than one ion, you write a subscript after the element. Mg2+ + F1- +F1- → MgF2 Coefficients indicate that you must multiply the species by that number. Mg2+ + 2F- → MgF2

  7. Cross-Balancing Charges For compounds that have multiples of each atom, you can cross the charges as coefficients (then subscripts). Al3+ + O2- → ? 2Al3+ + 3O2- → Al2O3

  8. Balancing Compounds Practice 1) What compound would be formed when the following ions bond? Cl1- Ca2+ CaCl Ca2Cl CaCl2

  9. Balancing Compounds Practice 2) What compound would be formed when the following ions bond? P3- K1+ KP K3P KP3

  10. Balancing Compounds Practice 3) What compound would be formed when the following ions bond? O2- Fe3+ Fe2O3 FeO Fe3O2

  11. Naming Compounds The compounds are named as they are written, not including subscripts. MgS magnesium sulfide AlF3 aluminum fluoride

  12. Naming Compounds Practice 4) What is the name of the salt, AgCl? silver chlorine silver chlorate silver chloroxide silver chloride

  13. Naming Compounds Practice 5) What is the name of the salt, BaO? barium oxide boron oxide baride oxygen barium oxygen

  14. Naming Compounds Practice 6) What is the name of the salt, Al2S3? aluminum trisulfite aluminum sulfate aluminum sulfide aluminum (II) sulfide

  15. Writing Compounds from Names Translate the name of each ion into the symbol form based on valence electrons. phosphide sodium P3- Na1+ Add coefficients to balance charges. → P3- 3Na1+ Na3P Rewrite as the chemical formula.

  16. Writing Compounds Practice 7) What is the chemical formula for potassium iodide? PI KI KI2

  17. Writing Compounds Practice 8) What is the chemical formula for beryllium oxide? BeO Be2O BeO2

  18. Writing Compounds Practice 9) What is the chemical formula for strontium bromide? SrBr2 Sr2Br SrBr

  19. Writing Compounds Practice 10) What is the chemical formula for calcium nitride? CaN Ca2N3 Ca3N2
