Presentation Transcript


  • When Metals combine with non metals planet?

    • 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


When naming ionic compounds with transition metals
When naming Ionic compounds with Transition metals planet?

  • 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


How do you know the type of lead being used
How do you know the type of Lead being used? planet?

  • 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


Name the following
Name the following planet?

  • PbBr2

  • PbBr4

  • LiCl

  • MgO

    Lead(II)Bromide

    Lead(IV)Bromide

    Lithium Chloride

    Magnesium Oxide


What about those crazy polyatomic ions
What about those crazy Polyatomic Ions? planet?

  • 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


There are rules for naming these as well
There are rules for naming these as well planet?

  • 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.


  • Name the following planet?

  • Cu(NO3)2, PbCO3, NH4I NaCN

  • Copper(II) Nitrate, Lead(II) Carbonate, Ammonium Iodide, Sodium Cyanide


Compounds that contain non metals molecules
Compounds that contain non metals(molecules) planet?

  • 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


  • Prefixes are planet?

  • 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


  • Ex: planet?

  • CO2

  • Name is Carbon dioxide

  • N3O5

  • Name is trinitrogenpentoxide

  • PCl3

  • Name is Phosphorous trichloride


  • Try These planet?

  • I2O7, CF4,IF5

  • Diiodineheptoxide, Carbon tetrafluoride, Iodine pentafluoride


  • Name the following planet?

    • 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
