The Periodic Table - element word search game

Here's a simple word search based on groups in the periodic table. Select a group number to start the game. All you have to do is find the names of the elements in the grid - they may be left to right, right to left, up, down and in any 45 degree angle. Drag with your mouse over the letters to select a complete element name - it has to be exact - and if you are correct move on to another element.

Oh... and I've included Hydrogen in Group 1. If you object to this.... let me know.
