Which of the following is a characteristic of an ion with a negative charge?

Anion
Alkali
Cation
Hydrophilic

The correct answer is: Anion

An anion is a negatively charged ion. In chemistry, ions are atoms or molecules that have gained or lost electrons, resulting in either a positive or negative charge. When an atom gains one or more electrons, it becomes a negatively charged ion, known as an anion. Therefore, the correct answer is A. Options B, C, and D are not characteristics of an ion with a negative charge. Alkali refers to a group of elements on the periodic table, cation is a positively charged ion, and hydrophilic refers to substances that are attracted to water.
