Atoms and Their Electrical Charges

What happens to an atom that loses or gains electrons?

A. It becomes an Isotope
B. It becomes a Proton
C. It becomes a Neutron
D. It becomes an Ion

Answer:

D. It becomes an Ion

Atoms are the basic building blocks of matter, composed of protons, neutrons, and electrons. An atom that loses or gains electrons is called an ion. When an atom loses electrons, it becomes positively charged and is called a cation. On the other hand, when an atom gains electrons, it becomes negatively charged and is called an anion.

Ions play a crucial role in chemical reactions and the behavior of compounds. They are responsible for the formation of salts, acids, and bases, among other compounds. Understanding the concept of ions is essential in various fields, including chemistry, biology, and physics.
