Ionic Compound Formulas

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. It typically consists of a metal cation and a nonmetal anion.

How do you determine the formula of an ionic compound?

Back

To determine the formula of an ionic compound, balance the total positive charge from the cations with the total negative charge from the anions. The resulting formula reflects the ratio of ions.

What is the formula for the ionic compound formed between aluminum and oxygen?

Back

The formula is Al2O3.

Front

What is the naming convention for ionic compounds?

Back

The cation is named first followed by the anion. The anion's name is modified to end in '-ide' for simple anions.

Front

Which elements typically form cations?

Back

Metals typically form cations by losing electrons.

Front

Which elements typically form anions?

Back

Nonmetals typically form anions by gaining electrons.

Front

What is the significance of the subscripts in an ionic compound formula?

Back

Subscripts indicate the number of each type of ion in the compound, ensuring the overall charge is neutral.

Front

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion, while an anion is a negatively charged ion.
