RefEls 1.0

RefEls is a Perl script that lets you look up and increase knowledge of the periodic table of elements. For all of the elements on the table the name, symbol, atomic number, and atomic weight have been referenced (the atomic weights for some elements are only those of the most common or well known types of the element, and may not be the only possible atomic weight).

There are two functions in the program. One is used to look up information about elements, and the other is a function like flash cards that allows you to test and improve your knowledge of the elements.

The reference section is used by typing in an attribute of an element, and then getting all of the information referenced about that element. You can type in the name, symbol, atomic number, or atomic weight to get the information about an element.

The flash card section works like normal cardboard flash cards: you are given one quality of an element and you have to give another quality of the same element back. One example would be the computer giving you the name of element and you having to give the atomic number for that element.
