Naming Ionic Compounds: Simple Ions and Polyatomic Ions

Multiple Choice

Which of the following endings is commonly used in naming ionic compounds?

• -ide

• -ous

• -ium

• -ene

Multiple Choice

Which of the following best describes how ionic compounds are formed?

• Metals and non-metals share electrons equally

• Metals give electrons to non-metals, forming ions that stick together

• Non-metals give electrons to metals, forming molecules

• Metals and non-metals combine without transferring electrons

Open Ended

Explain why ions tend to be stable, using the concept of electron arrangements and the periodic table.

Multiple Choice

Which of the following are correct steps for naming a simple ionic compound?

• Write the non-metal name first, then the metal name

• Write the metal name first, then the non-metal name with the ending changed to -ide

• Write both names unchanged

• Write the metal name first, then the non-metal name with the ending changed to -ate

Multiple Select

Which of the following are examples of polyatomic ions?

• SO4^2- (sulfate)

• Na+ (sodium ion)

• NO3^- (nitrate)

• Cl^- (chloride ion)

Multiple Choice

What is the difference between polyatomic ions ending with -ate and those ending with -ite?

• -ate ions have fewer oxygen atoms than -ite ions

• -ate ions have more oxygen atoms than -ite ions

• -ate ions are always negatively charged, -ite ions are positively charged

• -ate ions are found only in organic compounds
