Intro to Matter
• Everything around you is composed of matter.
• Besides matter, energy is the other major component of our universe.

Matter
• Matter is anything that occupies space and has mass.
• Some matter is easy to see (water, wood), others are difficult (air, dust).
• The most basic building block of matter is the atom.

Atoms and Molecules
• atoms: submicroscopic particles that are the fundamental building blocks of all matter.
• Sometimes, atoms are bonded together to form molecules.
• molecules: two or more atoms joined to one another in specific geometric arrangements.

States of Matter
• Matter can be classified by its state.
• solid: closely-packed particles with fixed locations
• liquid: closely-packed particles, but free to move around
• gas: great distances between particles with free movement

Pure Substances and Mixtures
• Matter can be classified by its composition.
• pure substance: matter composed of only one type of atom or molecule
ex. Helium & H2O
• mixture: matter composed of two or more pure substances that may vary in proportion but maintain their identities
ex: salt water Smog (smoke+ fog)
Mud puddle (dirt + water)

Mixtures • Most matter exists in this form.
• heterogeneous: varied composition from one region to another (different / can be seen) - sand
• homogeneous: uniform composition throughout
• (same / difficult to see particles) – water/air
particles are evenly dispersed

Types of Mixtures:
• Homogenous Mixture:
– particles are evenly dispersed.
– Cannot see particles.
– Solution
• Heterogeneous Mixture:
– Particles are dispersed.
– Can see particles.
– Suspension
– Colloid
