Study Notes

Composition of Matter

Matter is composed of tiny particles known as atoms.
Atoms serve as the building blocks of matter.

Structure of Atoms

Atoms consist of a nucleus that contains:
- Protons with a positive charge.
- Neutrons that have no charge.
Electrons, which carry a negative charge, orbit the nucleus and are smaller than protons and neutrons.

Elements

An element is defined as a substance made solely of one type of atom.
Each element has a unique number of protons, which distinguishes it from other elements.
The atom is the smallest unit of an element that retains its physical and chemical properties.

Properties of Subatomic Particles

Nucleus: The central core of the atom.
Protons: Positively charged particles found in the nucleus.
Neutrons: Neutral particles located in the nucleus, contributing to the atomic mass.
Electrons: Negatively charged particles that occupy space around the nucleus.

Examples of Elements

Common elements include oxygen, gold, copper, and carbon.

Stability of Elements

Elements are indivisible; they cannot be broken down into simpler substances.
