Example: "Which are the transition metals that condense in an fcc lattice?"

The unique marking feature of Element™

• Boolean logic

  The unique marking feature of Element™ allows the combination of properties by means of the Boolean criteria AND, OR and NAND.

  This makes it possible to easily identify any subset of elements with a certain set of common properties, such as the one given in the example: "Which are the transition metals that condense in an fcc lattice?".

• User friendliness

  Element™ provides several features that make the identification of marked elements effortless. By means of additional scroll buttons, only those elements marked can be stepped through.

  This makes it extremely easy to compare properties (such as electron configuration) for a set of pre-selected elements without taking your eyes off the details list at the bottom of the display.

• Intelligent interface

  Not only does Element™ provide an "undo" feature to take back a mistakenly performed marking action, but Element™ has also the intelligence to set its Boolean criteria to those that you are most likely to use.
