Classifying Matter

ACID-substance that yield hydrogen ions (H+) when dissolved in water

BASE-substance that yield hydroxide ions (OH) when dissolved in water

COLLOID-a dispersion of particles of one substance throughout a dispersing medium made of another substance

COMPOUND- substance composed of atoms of two or more elements chemically united in fixed proportions

ELEMENTS- substance that cannot be separated into simpler substances by chemical means

HETEROGENEOUS MIXTURE-the individual component of a mixture remain physically separated and can be seen as separate components

HOMOGENEOUS MIXTURE- the composition of mixture, after sufficient stirring, is the same throughout the solution

INORGANIC COMPOUND-compounds other than organic compounds

MATTER- anything that occupies space and has mass

METAL-element that are good conductor of heat and electricity and have the tendency to form positive ions in ionic compounds

METALLOID- element with properties intermediate between those of metals and non-metals

MIXTURE-combination of two or more substances in which the substances retain their identity

NON-METAL- element that usually poor conductors of heat and electricity

ORGANIC COMPOUND-compounds that contain carbon, usually in combination with elements such as hydrogen, oxygen, nitrogen and sulfur

OXIDES-substances that contains at least one oxygen atom and one other element in its chemical formula

SALTS is the product of the reaction between an acid and a base (other than A water). An inorganic salt is just any salt that doesn't contain carbon.

SOLUTION-A homogeneous mixture of two or more substances

SUBSTANCE- a form of matter that has a definite or constant composition

SUSPENSION- heterogeneous mixture in which relatively large particles scattered through solid, liquid, gas and it is bigger than solution and colloid
