6.2 Work Naming Ionic Compounds With Polyatomic Ions

Why are they called polyatomic ions?

• They can form many different types of ions.

• They are especially common ions, so there are many of them.

• They are groups (many) atoms that are bonded together and act together as an ion.

Which part of an ionic compound with polyatomic ions name gets written first

• Non-metal

• metal

• transition metal

• roman numeral

• polyatomic ion

Which part of an ionic compound with a polyatomic ion name gets written second?

• Non-metal

• metal

• transition metal

• roman numeral

• polyatomic ion

What should the non-metal name end in, for a polyatomic ion compound?

• ite

• ide

• ate

• ium

How should a polyatomic ion be treated?

• as individual elements

• as one element

• the same as a regular binary compound

• the same as 7 times red

When adding a subscript to a polyatomic ion, you should...

• multiply any subscripts on the polyatomic ion by the subscript you are adding

• put perenthesis () around the polyatomic ion before adding a subscript

• write the new subscript next to any subscripts on the polyatomic ion

• put the polyatomic ion in square brackets before adding the subscript

If you have 3 molecules of SO₄ how would you write it?

• SO_{4 3}

• 3SO₄

• (SO₄)₃

• 3(SO₄)₃

• SO₄₃
