There is tons of information known about each and every element known to mankind, but accessing it is another story. Most of it is scattered by the winds throughout the internet, some appearing on Wikipedia’s info boxes but most hidden throughout the mountains of text one might expect to find between the Indian subcontinent and the rest of Asia. pElement is one easy-to-use program that brings it all together in one place, allowing you to view detailed chemical, electrical, and nuclear information about every element on the table.
pElement is by default just a periodic table that has nothing but element names and numbers. Click on an element, however, and you open up a huge database of information about that element that any chemist would love. There are six categories of information, ranging from general physical properties to crystal structure information and even general nuclear information about them.
The real meat of the program, however, is within each category. On the bottom are small arrows allowing you to flip through pages upon pages within each category: what are the natural isotopes of Beryllium? The 3rd ionization energy of Germanium? It’s all contained within the tiny windows.
That’s not all, however. Also packed into pElement are a nice search tool–handy if you know the abbreviation but don’t want to take the time to find it in the vast table before you–and even some handy tools such as a list of constants, a list of metric prefixes, unit conversion, and notes about various subjects.
Though you won’t find it winning your local beauty pageant, pElement is the ultimate resource for anyone who’s either a chemist or taking chemistry classes. It’s packed as full as possible with as much information as either it or you can handle, and is entirely free to use.
