Hello, I'm CLCStudent. I wanted to let you know that one or more of your recent contributions have been [ disallowed by an edit filter] because they did not appear constructive. Please take some time to familiarise yourself with our policies and guidelines. You can find information about these at our welcome page, which also provides further information about contributing constructively to this encyclopedia. If you only meant to make test edits, please use the sandbox for that. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page. Also feel free to ask for assistance at the Help Desk whenever you like to. Thank you. CLCStudent (talk) 12:16, 2 July 2020 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did at Group (periodic table). Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. CLCStudent (talk) 12:17, 2 July 2020 (UTC)
