  1. Can you finish secret agent beakers task to save your planet?

  2. There are rules for naming!!

  3. When Metals combine with non metals • Metal loose one or more electron (becomes cation Ex: Mg2+) • Non metal gains one or more electrons (becomes anion Cl-) • These are called binary compounds • Cations are always named first • Anions are always second • Have an ide ending • Ex” NaCl Sodium Chloride

  4. When naming Ionic compounds with Transition metals • When metals form more than one ion there are different rules(Transition Metals) • Ex Pb forms Pb2+ and Pb4+ • We must distinguish what type of Lead we are talking about • Scientists use a roman numeral to distinguish what type of a metal is being used

  5. How do you know the type of Lead being used? • You must examine how the ions combined • All Compounds are neutral so in PbO2 the Pb ions must balance the O2- ions. • It must be Pb(IV) because there are 2 O ions (from 2 subscript). • Thus PbO2 is called Lead(IV)Oxide

  6. Name the following • PbBr2 • PbBr4 • LiCl • MgO Lead(II)Bromide Lead(IV)Bromide Lithium Chloride Magnesium Oxide

  7. What about those crazy Polyatomic Ions? • Polyatomic ions are ions that are composed of more than one element • Together they contain a charge • Ex- OH-= Hydroxide has a charge of -1 • NH4+ = Ammonium has a charge of +1 • SO42-= Sulfate and has a charge of -2

  8. There are rules for naming these as well • YOU MUST LEARN TO RECOGNIZE POLYATOMIC IONS • Similar to rules for naming binary ionic compounds • Cation first then anion, but no ide • Ex: NaOH= Sodium Hydroxide • Must distinguish what type of metal it contains • Ex Fe(NO3)3 = Iron(III)Nitrate • When writing polyatomics you must put use parenthesis to determine HOW MANY of each poly atomic.

  9. Name the following • Cu(NO3)2, PbCO3, NH4I NaCN • Copper(II) Nitrate, Lead(II) Carbonate, Ammonium Iodide, Sodium Cyanide

  10. Compounds that contain non metals(molecules) • There are different rules when a compounds contains only nonmetals • Ex: B,C,N,O,F, • The first element in the formula is named first,and the full element name is used • The second element is named as though it were an anion • Prefixes are used to tell the number of atoms present

  11. Prefixes are • Mono-1 • Di-2 • Tri-3 • Tetra-4 • Penta-5 • Hexa-6 • Hepta-7 • Octa- 8 • Note, mono is not used when describing the first atom

  12. Ex: • CO2 • Name is Carbon dioxide • N3O5 • Name is trinitrogenpentoxide • PCl3 • Name is Phosphorous trichloride

  13. Try These • I2O7, CF4,IF5 • Diiodineheptoxide, Carbon tetrafluoride, Iodine pentafluoride

  14. Name the following • BF3, NaCl, CCl4, FeS, AlBr3,N2O5, CuCl Na2SO4, KI Boron trifluoride, Sodium Chloride, Carbon tetrachloride, Iron(II) Sulfide, Aluminum bromide dinitrogen pentoxide,, Copper(I)Chloride, Sodium Sulfate, Potassium Iodide
