Ionic Compounds: Naming & Formula Writing

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. They typically form between metals and nonmetals.

Front

How do you determine the formula of an ionic compound?

Back

To determine the formula of an ionic compound, combine the symbols of the ions involved, using the charge of each ion to balance the overall charge to zero.

What is the charge of a rubidium ion (Rb⁺)?

Back

The charge of a rubidium ion (Rb⁺) is +1.

Front

How many total electrons are in a rubidium ion (Rb⁺)?

Back

A rubidium ion (Rb⁺) has 36 total electrons.

Front

What is the significance of the octet rule in ionic bonding?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to the formation of stable ionic compounds.
