Atoms

Definition

Atoms are the basic building blocks of matter. They are the smallest units of an element that still retain the chemical properties of that element.

Analogy

Think of atoms as Lego bricks. Just like how you can build different structures using Lego bricks, all matter is made up of different combinations and arrangements of atoms.

Atomic Theory: Atomic theory is a scientific explanation that describes the structure and behavior of atoms. It states that atoms are composed of a central nucleus containing protons and neutrons, with electrons orbiting around it in specific energy levels.

Electron Energy Levels: Electron energy levels refer to specific regions or shells around an atom's nucleus where electrons can be found. These energy levels determine the amount of energy an electron possesses.

Subatomic Particles: Subatomic particles are the particles that make up an atom, including protons, neutrons, and electrons.
