Matter
|
Something that has mass and exists as a solid, liquid, gas, or plasma
|
|
|
Energy
|
The capacity for work or vigorous activity: vigor: power
|
|
|
Atom
|
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons that entire structure has an approximate diameter of 10-8 centimeter and characteristically remains undivided in reactions except for limited removal, transfer, or exchange of certain electrons
|
|
|
Molecule
|
The smallest particule of a substance that retains the chemiscal and physical properties of the substance and is composed of two or more atoms: a group of like or differenct atoms held together by chemical forces.

Ion
|
an atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons
|
|
|
States of Matter
-Solid |
A substance having a defininite shape and volume; one that is neither liquid nor gaseous
|
|
|
States of Matter
-Liquid |
The state of matter in which a substance exhibts a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility
|
|
|
States of Matter
-Gas |
The state of matter distingusihed from the solid and liquid states by relatively low density and viscosity, reatively great expansion and contraction with changes in pressure and temperature, the ability to diffuse readily, and the spontaneous tendency to become distributed uniformly thoughout any container
|
|
|
Element
|
A substance compose of atoms having an identical number of protons in each nucleus. Elements cannot be reduced to simpler substances by normal chemical means
|
|
|
Compound
|
A pure, macroscopically homogeneous substance consiting of atoms or ions of two or more differenct elements in definite proportions that cannot be seperated by physical means. A compound usually has properties unlike those of its constituent elements
|
|
|
Solution
|
A homogenours mixture of two or more substance, which may be solids, liquids, gases, or a combination of these
|
|
|
Mixture
|
A compostion of two or more substances that are not chemically combined with each other and are capable of being separated
|
|
|
Physical Property
|
a property used to characterize physical objects
|
|
|
Chemical Property
|
a property used to characterize materials in reactions that change their identity
