App Description

Version 2.0 is the culmination of many years of development and experimentation.

It has everything a young scientist interested in chemistry should need to apply chemistry in school and in the real world.

We know that many adults have fond memories of wishing for a chemistry set when they were a child and the lucky ones got their wish on a special holiday or birthday. This app gives you (and your child) far more than a box of chemicals (and difficult instructions) might give you.

It gives you a solid working knowledge of chemistry without exploding in your face!

JR's Chemistry Set makes chemistry interesting and fun to learn. It is a handy and powerful reference tool for chemistry enthusiasts and practitioners at all ages and all levels.

It contains an interactive periodic table based upon the innovative Rota Period. With this app you can easily combine elements into chemical compounds and display the formulas using physics and touch control.

The main game component is called Mad Scientist and it challenges you to make valuable compounds like Water, Sodium Hydroxide and Hydrogen Peroxide. The quest in the game is to build a rocket ship. You are scored on your ability and these results are displayed in Game Center. In addition, all chemical compounds you create, are stored in the Library for future reference.

You can also pay to skip a level if you are unable to solve the puzzle!

There is also a series of scenes called Evolution that uses chemistry and particle physics to describe the universe from the Big Bang to Black Holes, providing the link between chemistry, physics, biology and astronomy.

Detailed information about all of the chemical elements are provided including:Atomic Number, Atomic Weight, Melting Point, Boiling Point, Heat of Fusion, Heat of Vaporization, Heat of Atomization, Ionization Energy, Electrical Conductivity, Electronegativity, Ionic Radius, Van der Waals Radius, Density, Class, Valences, Orbitals, State, Radioactivity and Year Discovered.

And now, you can share all of this information (and the fun of if) with others using Facebook, Twitter and Sina Weibo.

Available in 17 languages including: English, Spanish (Español), French (Francés), German (Deutsch), Portuguese (Português), Italian (Italiano), Danish (Dansk), Dutch (Nederlands), Finnish (Suomen), Norwegian (Norsk), Swedish (Svenska), Japanese (日本人), Chinese (中国), Korean (한국어), Greek (ελληνικά), Arabic(العربية) and Russian(русский)!
