Atoms

Atoms are the basic building blocks of matter, consisting of protons, neutrons, and electrons. The atomic number and mass number define the element and its characteristics, while atoms combine to form molecules and participate in chemical reactions. Understanding atoms is essential for grasping the principles of chemistry and physics.

Atoms are the basic building blocks of matter, consisting of three main parts:

Structure

1. *Protons*: Positively charged particles in the nucleus (center).

2. *Neutrons*: Particles with no charge in the nucleus.

3. *Electrons*: Negatively charged particles orbiting the nucleus.

Key Characteristics

1. *Atomic number*: Number of protons defines the element.

2. *Mass number*: Total number of protons and neutrons.

3. *Chemical properties*: Determined by the number of electrons.

Importance of Atoms

1. *Fundamental units*: Atoms combine to form molecules and compounds.

2. *Chemical reactions*: Atoms interact and bond with each other.

3. *Basis of matter*: Atoms make up everything around us.

Atoms are the foundation of chemistry and physics, and understanding them helps us grasp the world of
matter and energy!
