Hello, I'm KN2731. An edit that you recently made to Orbital hybridisation seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page.   ~ KN2731 {talk · contribs} 06:27, 21 November 2021 (UTC)
