Mass Defect
Sum of atomic weight and individual nucleons.
Isotopes
Two or more nuclides with the same atomic number, different mass number, always belong to same chemical elements
Isomers
two or more nuclides with same atomic number, same mass numbers. Different value of energy content. Always belong to same element
Isotones
Tow or more nuclides with different atomic numbers, SAME number of neutrons, always belong to different elements
Isobars
Two or more nuclides with the SAME MASS NUMBER, DIFFERENT ATOMIC NUMBER, always belong to different elements.
BOHRS Basic concept of a atom and its make-up
An atoms make up is similar to that of the Solar System
Nuclide
Atomic nucleus specified by its atomic number, atomic mass, and energy state
Electron
Negatively charged subatomic particle with approx mass of 9.11 X 10 E 37kg
Neutrons
Electrically neutral subatomic particle with approx mass of 1.675 X 10 E-27kg
Protons
Positively charged subatomic particle with approx mass of 1.673 X 10 E-27kg
Nucleons
Particles that make up the nucleus of an atom
Nucleus
Positively charged central region of an atom made up of protons and neutrons, and containing most the mass of an atom
Atom
Smallest fragment of a particular element that is still recognizable as such
Rest Energy
Energy and object has by virtue of its mass alone
Kinetic Energy
From of energy associated with motion of a body
Potential Energy
Stored or reserved energy
Momentum
Force which a moving body has because of it's mass and motion
Energy
Property something has which enables it to do work
Power
Time rate at which work is done by a force
Work
Measure of the amount of change that a force produces when it acts on a body
Weight
Effect that gravity has on mass of a body. Weight is there fore a force.
Mass
Describes the inertial property of bodies and is defined as the quantity measure's of inertia
Centrifugal force
The reaction force that provides an outward pull on the axis
Centripetal Force
The inward force that must be applied to keep a body moving in a circle (towards the center of the circle)

(described by newtons third law)
Centripetal Acceleration
Acceleration directed toward the center axis or curved path and arises from continually changing direction of a body about the axis
Three types of Accelerations
Speed Increase
Speed Decrease
Change in direction of the body
Acceleration
Rate of change in velocity
Velocity
Quanity describes both how fast and what direction a body is moving
