Properties of Ions

What is an ion?

An atom that has gained or lost an electron ___________. (a). enzyme (b). ion (c). isotope (d). molecule

Answer:

Ion

An ion is an atom that has gained or lost one or more electrons, resulting in a positive or negative charge. When an atom loses an electron, it becomes positively charged, known as a cation. On the other hand, when an atom gains an electron, it becomes negatively charged, known as an anion.

Ions play a crucial role in various chemical reactions and biological processes. They can easily form bonds with other ions or molecules to achieve stability. For example, sodium ion (Na+) and chloride ion (Cl-) combine to form table salt (NaCl).

Understanding the properties of ions is important in fields such as chemistry, biochemistry, and environmental science.
