=**This is Block 3's Atomic Internet Hunt Page: TEAM A**= Remember the rules:
 * **NO** deleting of other teams information allowed!
 * If your team believes information is incorrect, you may make an additional post underneath other teams.
 * You must end your post with your teams name/initials for the points to count.
 * Not all information posted is worth the same amount of points. Posting pictures is tougher to do than editing text, so pictures are worth more.

Practice: a. Post something here by editing regular: b. Post an image here by signing in and uploading a file/image: c. Link the word link to the homepage: (gschemistrybp.wikispaces.com)
