ChemTab - A Periodic Table (of the elements) Database

Chemtab was written at Lincoln-Sudbury Regional High School during the 1989
to 1990 school year.  The student, Jim King, our graduating high-hopes
programmer will be attending Rochecter Institute of Technology during the
next five school years studying Computer Science (Networking).

Chemtab was designed in conjunction with the faculty in the science
department at the Lincoln-Sudbury Regional High School.  The database does a
variety of functions:

	1) Graph elemental data (x vs y)
	2) Select a set of elements from given parameters
	3) Look at a certain element and display all known information
	   (at least, all input data) on the element.

All elemental information in this program has been extracted from the
following source:
	CRC Handbook of Chemistry & Physics, 63rd edition, 1982-1983

o All whole numbers, if rounded, are rounded on the premise that:
  .01 to .49 considered rounded down
  .50 to .99 considered rounded up

o Ionization Energy found in the following manner: (to compromise the
  chemistry courses at L-S)
	All figures based on the table of "IONIZATION POTENTIALS", pages
	E-64 and E-65, column I, then multiplied by 23.  Rounded.
