Welcome to Charged Up! THE chemistry review App. Charged Up! has many useful features that will aide you as you study the elements and radicals. Under the Study This! label, you will find both element and radical lists which are searchable for easy access. Clicking on the elements will give you their symbol, atomic mass, electron structure, and state of matter. Doing the same for the radicals will give you their oxidation states.

Not only are these lists searchable, they are printable as well. Just click on the corresponding list under Print This! and, if an air-print printer is available, you can make yourself a hard copy to study from.
Once you know all the charges, it is time to PLAY THE GAME! Make your character jump around the playing field collecting the correct charges and avoiding the wrong ones. Each correct charge gives you life and points, while you lose life and points for colliding with the wrong ones, so choose your path wisely.

Getting interrupted while playing is no problem. Simply swipe up on the game field to quit the game and return to the start-up screen or swipe to the right to pause the game.

Don’t forget to set up what kinds of charges you want to be tested on! In the set-up menu, you can select the number of test items in your game. Elect only elements, only radicals, or a little of both, it’s up to you. All of your high scores will be recorded so you can compete with your friends for high scores and better grades!

What's New

Version 1.2

We have changed a couple of things in this newest version. First, we have created a slider in the set up menu so you can control the motion of the character. Place the slider closer to the turtle and you will slide slowly. Place it near the rabbit and you will slide quickly across the playing field, it is up to you.

Also, we have made it possible to rearrange the lists. Since the test generator takes the very first elements or radicals, you can place all the items you want to be tested on near the front. So when you play the game, only the items you want to be test on will show up!

Amazing app

William Schoneman

This app has charged up my life. It has helped me a lot in chemistry class. I highly recommend this to anyone interested in getting a good grade in chemistry.



The triangle character is pretty difficult to control. Every time I played it slid into almost all the charges and ended up falling to the bottom...But the lists and electron configurations of the elements and radicals were helpful.



This app is awesome. Great way to study for my Chem quizzes. Wish there was more apps like this out there
