- If this is a shared IP address, and you didn't make any unconstructive edits, consider creating an account for yourself so you can avoid further irrelevant warnings.
Please refrain from making unconstructive edits to Wikipedia, as you did to Talk:Electron configuration. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Thank you. DMacks (talk) 21:06, 18 November 2007 (UTC)
