Naming Compounds By Lexie Zovko, Andrew Wang, Sarah Houy, and Zach Lesutis

Compounds  Is there a metal? Yes! The compound is ionic No! The compound is Covalent Periodic table

Yes! The compound is ionic  Is there a polyatomic ion?  See list of polyatomic ions No there is not a polyatomic ion Yes there is a polyatomic ion Polyatomic ions

No there is not a polyatomic ion  What is the first element? Continue: Write the name of the first element

Yes there is a polyatomic ion  Where is the polyatomic ion? BeginningEnd

Write the name of the first element  Is the first element a transition metal?  See periodic table. They are listed in the d-block. Yes it is a transition metal No it is not a transition metal Periodic table

Beginning  Write the name of the polyatomic ion normally. Then name the other element after. The other element should end in -ide Continue: Name the element

End  Write the name of the first element without changing the name. Then name the polyatomic ion after the first element. Continue: Name the element

Name the element!  Examples KSCN Al(NO2)3 FeSO4 Ni(OH)3 NaNO3 Fe3(PO4)2 NH4C2H3O2Ca[Fe(CN)4] Na3PO4 NH4Cl Ba(NO3)2 Mg(OH)2 Al(C2H3O2)3 KMnO4 Na3[Fe(CN)6] Cs(NO2) Li3PO4 Na2SO4

Yes it is a transition metal  List the name of the element and the charge used in roman numerals in parenthesis. Periodic table Continue: What is the name of the second element Transition Metal Examples

Transition Metal Examples SnO TiO2 FeS Cu2S SnO2 Fe2S3 PbS PbO2 Cu2SO4 PbO

No it is not a transition metal  List the name of the element used. Continue: What is the name of the second element

What is the name of the second element  List the name of the element used, but change the ending to –ide. Continue:

 Is H 2 O mentioned in the formula? Yes H2O is mentionedNo H2O is not mentioned

Yes H 2 O is mentioned  Add the proper prefix followed by “hydrate” (See prefix table) Prefix Chart Continue: Name the element!

No H 2 O is not mentioned  Leave the name as it is Continue: Name the Element!

KI MgH2 H2S Li3N Ca3P2 ZnO MgS AgCl  Examples:

Name the element!  Examples CoCl2 6 H2OCoCl2 2 H2O Na2S2O3 5 H2OMgSO4 7 H2O

No! The compound is Covalent  Is this electronegativity difference less than.3? (See Periodic Table) Periodic tableYes the compound is pure No! The compound is polar

Yes! The compound is pure Continue:

No! The compound is polar ContinueContinue:

 What are the elements Continue: First element

 Find the prefix depending on the number of each atom used (See prefix table).  Write the prefix in front of the element used Prefix ChartContinue: Second element

 Find the prefix depending on the number of each atom used (See prefix table)  Write the prefix in front of the element, ending the element in –ide. Prefix ChartContinue: Name the element!
