1. Chem-To-Go Lesson 14 Unit 4 IONIC BONDING - NAMING Need a periodic table and an ion sheet

2. 1.Write the name of the metal element, which is the positive ion. 2.If the metal is a transition metal (except for Ag or Zn), draw parentheses for the Roman numeral. We’ll fill it in later. 3.Write the name of the negative ion. If it is a monatomic ion (a plain ol’ element), then the ending will be –ide. If it is a polyatomic ion, then the ending will be probably be –ite or –ate. 4.Fill in the Roman numeral. You’ll need to determine the ORIGINAL charge of cation. It’s that positive charge that goes in the parentheses. HOW TO NAME IONIC COMPOUNDS Al 2 (SO 4 ) 3

If the anion has more than one element, then it is a polyatomic ion.

It’s that positive charge that goes in the parentheses. EXAMPLE 4 CuF 2 Helpful Tip: Don’t ever backwards criss- cross to find the polyatomic ion. If the subscripts have been reduced, then you’ll make a mistake.
