Chemistry Properties and Structure of Matter: Properties of Matter - Naming Polyatomic Ions

This video tutorial covers the writing of chemical formulae and names for polyatomic ions and ionic compounds. It explains the rules for writing these formulae, including the use of parentheses for polyatomic ions, and provides examples such as barium nitrate and ammonium phosphate. The video also discusses naming conventions for ionic compounds, emphasizing the importance of memorizing common polyatomic ions. The tutorial concludes with a summary of the key points covered.

Why is it incorrect to write the subscript 2 without parentheses in the formula for barium nitrate?

What is the charge of the ammonium cation?

What modifications are made when naming monoatomic ions compared to polyatomic ions?

What is the final name of the compound with the formula (NH4)2S?
