ChemAP 2003 is a Periodic Table features 112 elements. It has more than 30 data items on each element, including abundance, melting and boilling points, electronegativity, more than 500 isotopes, history and more. The program includes utils to compare elements, calculate molecular weights, compare bond properties, list properties in sorted lists, graph the properties, unit convertion tool, etc. And more tables of constants, pH indicators chart, ionization constants, enzymes database, etc. Principal features: - Periodic Table - Find elements - Unit conversion tool (Temperature, mass, length, etc) - Compare elements - Atomic weight calculator - Search for elements by their names, symbols, weight, density, and others properties - Trend graph - Enzyme database - Ionization constants - Print information, save and copy results - Chemistry glossary - Ionization constants - ... and more (pH indicators chart, abundance...). ChemAP 2003 allows you to quickly find ionization energies, bond orders, isotopes and their weights, and much more. You can view elements that are metals, states, or groups. You can also view characteristics for each element. It is an extremely easy-to-use program and is a must-have if you are studying chemistry.
