SCIENTISTS,USE SOME WORDS TO DESCRIBE SCIENTIFIC CONCEPTS,
WE NORMALLY GIVE A DIFFERENT MEANING TO, AS EXPLAINED BELOW
EQUIVALENT
MEANINGS
( EQUAL MEANING )
  THEY SAY THE MASS OF THE OBJECT, WHEN THEY REALLY MEAN, THE WEIGHT OF THE OBJECT
MASS
=
 WEIGHT  
  THEY USE THE WORDS,THE MATTER,.TO DESCRIBE..THE MATERIAL OF A PHYSICAL OBJECT,
  THAT HAS A WEIGHT....AND A FORM....THAT TAKES UP SPACE....IN THE WORLD,INCLUDING,
  THOSE MATERIALS.THAT ARE LIQUIDS and GASES, NOT ONLY SOLID MATERIALS
THE MATTER
=
   THE MATERIAL  
  THEY USE THE WORDS, THE ELEMENT, TO MEAN,
  A PURE MATERIAL or THAT MATTER,THAT IS MADE OF ONE TYPE OF ATOM,
  WHICH IS COMPOSED OF ONE OF THE 89 NATURAL ATOMIC ELEMENTS
THE ELEMENTS
=
ATOMIC MATERIALS
  THEY USE THE WORD A  SUBSTANCE, TO MEAN A MATERIAL,.EVEN IF IT IS A LIQUID OR A GAS,
  INCLUDING ALL THE PURE ATOMIC MATERIALS and ALL MIXTURES OF THE ATOMIC ELEMENTS
SUBSTANCES
=
PRODUCTS
OR MATERIALS
  THEY USE THE WORD STATE,.TO DESCRIBE THE MANIFEST DENSITY...WHICH IS,
  THE HARDNESS, SOFTNESS, LIQUIDITY OR EXPANSIVE GASIOUSNESS OF MATERIAL THINGS
THE STATE
=
MANIFEST  DENSITY
THEY USE THE WORD, SATURATED, TO MEAN HAVING (N)CBN + (2N+2)HDR,  HYDRON ATOMS,
IN AN ALKANE..HYDRO-CARBON MOLECULE.                                  ( N = A NUMBER )
SATURATED
=
MORE HYDRON
THEY USE THE WORD, UNSATURATED, TO MEAN,HAVING LESS HYDRON ATOMS
THAN AN ALKANE HYDRO-CARBON MOLECULE OF AN EQUAL NUMBER OF CARBON ATOMS
UNSATURATED
=
LESS HYDRON
                                                                                                                                 ( HYDRON = HYDROGEN )



    IMPORTANT RELATED CHEMISTRY CONCEPTS   
 IT IS IMPORTANT TO REMEMBER THAT, ALL PHYSICAL MATERIALS,HAVE A CERTAIN DENSITY        
DENSITY
 MATERIALS ARE SOLIDS, IF THEY HAVE THEIR ATOMS,VERY CLOSELY PACKED TOGETHER
SOLIDS
 MATERIALS ARE GASES,   WHEN THEY HAVE THEIR ATOMS VERY FAR APART
GASES
 MATERIALS ARE PLASTICS or LIQUIDS
          WHEN THEY ARE A MIXTURE OF ATOMS THAT ARE GASES
                     or .ATOMS THAT ARE GASES and ATOMS,THAT ARE SOLIDS
PLASTICS
and
LIQUIDS

 RELATED CHEMISTRY....DENSITY CONCEPTS

 METALS HAVE THEIR ATOMS..VERY CLOSELY PACKED TOGETHER
METALS
 SEMI-METALS HAVE THEIR ATOMS...LESS CLOSELY SPACED
SEMI-METALS
 METALINES HAVE THEIR ATOMS...MUCH LESS CLOSELY PACKED TOGETHER
   ( LITION...BERILION....SODION...MAGNION...POTASION...CALCION )
METALINES
NON-METALS,
  HAVE THEIR ATOMS IN LAYERS OF ARENE RINGS,
  OR IN LAYERS OF DENSE CRYSTALLINE FORMS.
  ( CARBON....SULFURON....FOSFORON....SOLENION....TELORION  )
NON-METALS
 GASES OF ATOMS, THAT ARE GASES, AT OUR TEMPERATURE OF LIFE,
   HAVE SPACES BETWEEN THEM.
   3 TIMES GREATER THAN THEIR OWN DIAMETERS.
   (  HYDRON....FLORON....CLORON.....NITRON...OCSION.  )
GASES
 WHEN DIFFERENT TYPES OF GASES JOIN TOGETHER,
   THEY CREATE EITHER....OTHER GASES....OR  LIQUIDS
    (  HYDRO-CLORIC ACID...HYDRO-FLORIC ACID...HYDRO NITRIC ACID ~ AMMONIA  )
GASES
and
LIQUIDS
   MOLECULES OF TWO OR MORE GASES
    HAVE A RING OF SPACE AROUND THEM.... IN ONE DIRECTION...
    EQUAL TO THE DIAMETER OF THE SMALLEST OF THE ATOMS
    and ALMOST TOUCH IN THE OTHER DIRECTION               
MIXED
MOLECULAR
GASES
 GASES OF ATOMS,
   THAT ARE A MIXTURE OF GASIOUS and NON-METAL ATOMS
   HAVE SPACES BETWEEN THEM,
   AS WIDE AS THE MOLECULES THAT THEY FORM.
GASES
and
NON-METALS
 WHEN GASES,JOIN WITH NON-METAL ATOMS
   THEY FORM PLASTICS...OR...LIVING TISSUE
   (  HYDRON,.CARBON and CLORON = POLYVINYL CLORIDE )
PLASTICS
and
LIVING TISSUE
 WHEN GASES JOIN WITH METALS,
   THEY CREATE CRYSTALLINE SALTS
    OR THE ORES OF METALS
SALTS
and
ORES
WHEN GASES JOIN WITH SEMI-METALS
THEY FORM SAND, SALTS OR HALOGENIC ENZYMES
SAND, SALTS
and
ENZYMES
 WHEN WORKING WITH GASES,
LIQUIDS OR SOLIDS,
                                                                                    ONE MUST ALWAYS BE AWARE.
 GASES TEND TO EXPAND IN ALL DIRECTIONS
   and MUST ALWAYS BE CONTAINED.
       IN ADDITION,  
   ALL CONCENTRATIONS OF GASES ARE EXTREMELY POISONOUS TO HUMANS
GASES
 LIQUIDS, TEND TO WANT TO FLOW HORIZONTALLY, IN ALL DIRECTIONS,
   AND ALWAYS NEED CONTAINMENT ON THEIR SIDES
   and....EVEN MORE, SO ON THEIR BOTTOM.
LIQUIDS
 IF LIQUIDS ARE HEATED....THEIR ATOMS WILL EXPAND FROM 21 TO 1000 TIMES
 IF HEATED EXCESSIVELY, THE ATOMS IN LIQUIDS...CAN EXPAND SO MUCH
      THAT THE LIQUIDS, CAN BECOME, VERY EXPANSIVE GASES
             THAT CAN CAUSE, CLOSED CONTAINERS,TO EXPLODE.
HEATED
LIQUIDS
 SOLIDS REQUIRE...ENORMOUS AMOUNTS OF HEAT,
   TO CAUSE...THEIR ELECTRON ORBITALS. TO EXPAND ENOUGH,
   TO ALLOW THEM, TO BOND, TO OTHER METALS, SEMI-METALS OR GASES.
SOLIDS
THIS TYPE OF METAL CHEMISTRY IS CALLED METALLURGY
IT IS VERY DANGERIOUS and THEREFORE, IT IS DONE BY LAW, IN FOUNDRYS,
THAT HAVE SPECIAL, HIGH HEAT PROTECTIVE EQUIPMENT,
SUPERVISED BY LICENSED PERSONEL.
CARBIDES
METALS
SALTS
ORES

THESE ARE THE RECOMMENDATIONS OF THE BOARD OF DIRECTORS OF IUPAC
