Polyatomic Ions and Naming

Polyatomic Ions and Naming. Polyatomic ions. Polyatomic ions end in either –ite or –ate -ite indicates one less oxygen atom than an -ate. Unfortunately it does not tell you how many are actually in the polyatomic. Sulfite vs Sulfate SO 3 2- vs SO 4 2- You will look up on the table. .

  1. Polyatomic Ions and Naming

  2. Polyatomic ions • Polyatomic ions end in either –ite or –ate • -ite indicates one less oxygen atom than an -ate. Unfortunately it does not tell you how many are actually in the polyatomic. • Sulfite vs Sulfate SO32- vs SO42- • You will look up on the table.

  3. Compounds with Polyatomic Ions • When writing the formula make sure that you put parenthesize around the polyatomic. • Ca (NO3)2 • Ca2+ and NO3-
