Naming CompoundsBy Lexie Zovko, Andrew Wang, Sarah Houy, and Zach Lesutis

CompoundsIs there a metal?

Yes! The compound is ionic

No! The compound is Covalent

Periodic table

Yes! The compound is ionicIs there a polyatomic

ion?See list of polyatomic

ionsNo 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 ionWhere is the polyatomic ion?

Beginning End

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

BeginningWrite the name of the polyatomic ion normally. Then name the other element after. The other element should end in -ide

Continue: Name the element

EndWrite the name of the first element without changing the name. Then name the polyatomic ion after the first element.

Continue: Name the element
