There are millions of compounds. How are some of these compounds formed? They are the result of an arrangement of modified atoms called ions. Ions are atoms that have lost or gained electrons. When an ion transfers its electron, an ionic bond is formed. This quiz covers the basics on ionic bonding. Using what you have learned, complete this quiz. Select the best answer to the question.
