Hello, I'm Blaze Wolf. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Mendeleev's predicted elements—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse or the Help desk. Thanks. ― Blaze WolfTalkBlaze Wolf#6545 20:13, 9 September 2022 (UTC)
