Polyatomic Ions and Their Properties

The video tutorial by Doc Williams explains polyatomic ions, comparing them to monatomic ions. It provides examples like sulfate and sulfite, and discusses naming patterns and tips for memorization. The tutorial also covers scenarios with additional oxygen in ions and reviews hydrogen-containing ions. It concludes with a summary of tips for naming and memorizing polyatomic ions.

What is the main difference between a monatomic ion and a polyatomic ion?

• Monatomic ions have multiple types of atoms.

• Polyatomic ions have only one type of atom.

• Monatomic ions consist of a single type of atom.

• Polyatomic ions have no electrical charge.

Which suffix is used for a polyatomic ion with one less oxygen than the -ate form?

• -ite

• -ide

• -ine

• -ate

If a polyatomic ion has one more oxygen than the -ate form, which prefix is used?

• hypo-

• super-

• sub-

• per-

What is the correct name for NO3-?

• Nitrogen

• Nitride

• Nitrate

• Nitrite

Which of the following is a correct example of a polyatomic ion with a hypo- prefix?

• Hypochlorine

• Hypochlorite

• Hypochlorate

• Hypochloride

What is the name of the ion HSO3-?

• Sulfate

• Hydrogen sulfite

• Hydrogen sulfate

• Dihydrogen sulfite

Which prefix is used when a polyatomic ion contains two hydrogen atoms?

• bi-

• di-

• tri-

• tetra-

What is the name of the ion PO4 3-?

• Phosphine

• Phosphate

• Phosphite

• Phosphide

What is the suffix for most monatomic anions?

• -ide

• -ine

• -ate

• -ite

Which tip is useful for memorizing polyatomic ions with varying oxygen content?

• Memorize the hypo- form first.

• Memorize the per- form first.

• Memorize the -ate form first.

• Memorize the -ide form first.
