Matter An Insight Into The Structure and Properties of Matter
What Is Matter? Matter is anything that has mass and volume. A cup, pen, and eraser are made up of matter
What Is Matter? The definition of matter is often taken to mean anything composed of atoms and molecules. Thus, matter is anything made of protons, neutrons, and electrons.
Structure Of Matter The atom is the “building block of matter”. All substances are composed of invisible particles called atoms. Atoms are the building blocks of matter and are in constant motion. The combination of atoms leads to millions of materials with different properties.
Atoms Atoms are composed of three types of particles: protons, neutrons, and electrons.
Nucleus Atoms are made up of a positively charged center, the nucleus, containing: - Protons with a positive charge - Neutrons with no charge (neutral) O + O + = Neutron w/ Neutral Charge = Proton w/ Positive Charge Nucleus
Atom The electrons of an atom are found orbiting the nucleus of the atom Electrons have a negative charge

Phases of Matter Matter is classified into four phases or states Solid Liquid Gas Plasma
Solid Solids have definite: Mass Volume Shape
Liquid Liquids have definite Mass Volume No definite shape.
Plasma Plasma is the form of matter that exists when the atoms are in an excited state. Stars (the sun is a star) exist in the plasma state because of nuclear fusion. Some examples of plasma found on Earth are: lightning, auroras, and neon.
Review - Phases of Matter Gases' shape is determined by container and volume is determined by container. Liquids shape is determined by the container and has constant volume. Solids have constant shape and volume.
