MATTER
Anything that occupies space and has mass.
Structure of Matter
Modern physics has revealed successively deeper layers of structure in ordinary matter. Matter is composed, on a tiny scale, of particles called atoms. Atoms are in turn made up of minuscule nuclei surrounded by a cloud of particles called electrons. Nuclei are composed of particles called protons and neutrons, which are themselves made up of even smaller particles called quarks. Quarks are believed to be fundamental, meaning that they cannot be broken up into smaller particles.

States of Matter
Solid, atoms are tightly packed and very close to each other. Compact, has definite shape & volume. Liquid, atoms are less compact. It has definite volume but indefinite shape. It depends on the shape of its container. Gas, atoms are far from each other. It has indefinite shape & volume. It has great expansion capacity.
Changes in state of Matter
Other States of Matter Plasma, in physics, usually gaseous state of matter in which a part or all of the atoms or molecules are dissociated to form ions (see Ionization). Plasmas consist of a mixture of neutral particles, positive ions (atoms or molecules that have lost one or more electrons), and negative electrons. A plasma is a conductor of electricity, but a volume with dimensions greater than the socalled Debye length exhibits electrically neutral behavior.

Properties of Matter Physical property 1. Intensive property – properties that don’t depend on matter present. 2. Extensive property – properties that depend on matter present. Chemical property 1. Flammability/combustion 2. Reactivity with water (electrolysis) 3. pH 4. Electromotive force
Classification of Matter A.
Pure Substance 1. Element – substance made up of only one type of atom. Simplest form of matter. 2. Compound – made up of two or more types of atoms of elements. Elements are combined chemically in a definite proportion.
B. Mixtures – consist of two or more substances that are physically combined in no definite proportion by mass. 1. Homogeneous mixture – one phase a. Solution – a mixture of one substance dissolve in another so the properties are the same throughout. 2.Heterogeneous Mixture – two or more phases a. Suspension – a mixture between two substances, one in which is finely divided and dispersed in the other. b. Colloid – a mixture in which particles are smaller than a solution. They’re not uniformly dispersed all throughout and cloudy in appearance.
