Chemical Formula Tutor

Learn to write chemical formulas by dragging and dropping ions to balance in the Learn Mode. This edition has 4 Levels to work at. The Editor Edition allows cloning, adding deleting modifying and renaming of levels.

Move the mouse cursor, Hints display the name of the ion and the cursor shows its charge. Double Click or Drag ions to the balance, Hints will tell you what you need to do to balance the charges. When the charges are being balanced, the formula of the substance will be displayed in the formula frame and an atom counter shows numbers of each type of atom. To find out the name of the substance move the mouse cursor to the formula frame. To immediately show the formula, Drag the ions directly to the formula frame.

The Test Mode randomly selects ions from the Level you have chosen.

To Make the Test More Challenging: * Include or exclude Atom Counting Questions, * Testing can be done with or without the extra pressure of time, * You can set how long the timed test will run for, * Hide or Show the positive and / or negative ions
