^C^1PERIODIC TABLE
^Cby
^CSuzie DeMoss and George Leritte
Chemistry is one of the fundamental sciences. People in technical fields from
manufacturing to medicine must understand its basic principles. That's why
there are so many introductory chemistry classes in high schools and colleges.
One of the most important tools used to teach basic chemistry is the periodic
table -- the subject of this computer tutorial.
The periodic table dates back to 1869, when the Russian chemist, Dmitri
Mendeleev began arranging the elements known at the time into families --
elements that have similar chemical properties. For instance, with one
exception, the members of the halogen family -- fluorine (F), chlorine (Cl),
bromine (Br), iodine (I), and astantine (At) -- all exist as diatomic gasses
at room temperature.
Over the years, as scientists discovered other elements and learned about the
structure of atoms, more information was added to the table, filling in the
blanks left open by Mendeleev in anticipation of new finds.
By reading the periodic table, the student can learn any element's vital
statistics: the element's atomic number, its atomic weight, as well as other
information necessary to understanding how the element reacts with other
elements.
