Step 1:: Understand the definitions of cations and anions.
Cations are positively charged ions, while anions are negatively charged ions. They are formed when atoms gain or lose electrons during chemical reactions.
Step 2:: Identify the charges of cations and anions.
Cations have a positive charge because they lose electrons, which have a negative charge. Anions have a negative charge because they gain electrons.
Step 3:: Compare the given options with the definitions and charges of cations and anions.
Option A is incorrect because both cations and anions change in density as they cool, depending on their structure and the specific material. Option B is incorrect because both cations and anions can have absolute charges greater than one, depending on the number of electrons lost or gained. Option C is correct because cations have a positive charge, and anions have a negative charge. Option D is incorrect because magnetic properties are not directly related to the definition of cations and anions.
Final Answer
The difference between cations and anions is that cations have a positive charge, and anions have a negative charge.
