Interpretation: The cation and anion are to be distinguished.
Concept Introduction: Electrostatic interaction between ions in a compound with opposite charges forms an ionic bond.
Answer to Problem 95A
An anion is an ion that has a negative charge, in contrast to a cation, which is an ion that has a positive charge.
Explanation of Solution
An ion with a negative charge is an anion because it is attracted to an anode with a negative charge. An ion with a positive charge is a cation because it is attracted to a cathode with a negative charge. Cations and anions have opposite electric charges. Therefore, they are attracted to one another and may easily combine to form ionic compounds.
An anion is an ion that has a negative charge, in contrast to a cation, which is an ion that has a positive charge.
