Hello, I'm Flyer22 Reborn. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Inert pair effect—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 Help desk. Thanks. Flyer22 Reborn (talk) 01:41, 21 January 2020 (UTC)
