What kind of charge do anions have?

• A. Negative charge
• B. Positive charge
• C. Neutral charge
• D. No charge

Answer: (A)

Anions have a negative electrical charge because they gain electrons, giving the ion a net negative charge. This contrasts with cations, which have a positive charge from losing electrons, and neutral species that have no net charge. In soils, the negative charge of anions influences how they move and interact with soil surfaces, affecting processes like leaching and retention. Common examples of anions include nitrate, sulfate, and phosphate ions.
