Classification of Matter Set C

Examples of Matter designed to familiarize students with the properties that qualify samples for common categories.
STUDY
PLAY
Mixture
..., A combination of 2 or more substances that are not chemically combined
Homogeneous Mixture
..., A mixture in which substances are evenly distributed throughout the mixture
Compound
(chemistry) a substance formed by chemical union of two or more elements or ingredients in definite proportion by weight
Ionic Compound
..., Composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal
Heterogeneous Mixture
..., A mixture that is not uniform in composition; components are not evenly distributed throughout the mixture
Covalent Compound
..., a chemical compound formed by the sharing of electrons that begins with a nonmetal
Atom
..., Smallest unit of matter that retains the properties of an element
Solution
..., A liquid that is a homogeneous mixture of two or more substances.
Molecule
..., (physics and chemistry) the simplest structural unit of an element or compound
Suspension
..., A heterogeneous mixture containing a liquid in which visible particles settle.
Solute
..., In a solution, the substance that dissolves in the solvent
Colloid
..., A mixture made up of a liquid and particles that (because of their large size) remain suspended rather than dissolved in that liquid.
Solvent
..., Substance that does the dissolving
Metallic Element
Any of a category of electropositive elements that usually have a shiny surface, are generally good conductors of heat and electricity, and can be melted or fused, hammered into thin sheets, or drawn into wires. Located left of the zigzag in the periodic table.
Non-metallic Element
...Any of a number of elements, such as oxygen or sulfur, that lack the physical and chemical properties of metals. Located to the right of the zigzag in the periodic table.
Element
A pure substance made of only one kind of atom
Sulfur
Nonmetal element
