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.
