chemical bonds.


Atom - CORRECT ANSWER -Fundamental constituents of matter. The elements wich come
together in various combination to form molecules of many substances


Nucleus - CORRECT ANSWER -The center portion of an atom which has a positive electrical
charge



Proton - CORRECT ANSWER -Single positive electrical charge located in the middle of an
atom.



Electron - CORRECT ANSWER -Single negative electric charge orbits around the nucleus some
and Paths close to the nucleus others and Paths varying distance from the nucleus


Coulomb - CORRECT ANSWER -Certain quantity of electrons. The unit of measure that
specified the rate at which electric current flows per second


Bound Electrons - CORRECT ANSWER -Those electrons in orbit nearest the nucleus, not Easily
dislodged from their normal orbit.



Free electrons - CORRECT ANSWER -Those electrons in orbit farthest out from the nucleus,
loosely bound and migrate from one atom to another.
