Molecule
Smallest parts of substance can be physically divide into two
compose more Atoms. A molecule is a collection of atoms held
together by strong forces called chemical bonds.
Atom
Fundamental constituents of matter. The elements wich come
together in various combination to form molecules of many
substances

, Nucleus
The center portion of an atom which has a positive electrical charge
Proton
Single positive electrical charge located in the middle of an atom.
Electron
Single negative electric charge orbits around the nucleus some and
Paths close to the nucleus others and Paths varying distance from
the nucleus
Coulomb
Certain quantity of electrons. The unit of measure that specified the
rate at which electric current flows per second
Bound Electrons
Those electrons in orbit nearest the nucleus, not Easily dislodged
from their normal orbit.
Free electrons
Those electrons in orbit farthest out from the nucleus, loosely bound
and migrate from one atom to another.
Valance Electron
A single electron or one or two or more electrons in the outer shell of
and atom that is responsible for the chemical properties of an atom
Shells
Any of the space occupied by the orbit of a group of electrons of
approximately equal surrounding the nucleus of an atom
Static electric charge
Electric charge at rest Caused by friction of materials, where a a
surplus of electrons exists and may be discharged.
