Welcome!
Hi Jerzyewaz, and welcome to Wikipedia! Thank you for your contributions. I hope you like it here and decide to stay. Our intro page provides helpful information for new users—please check it out! If you have any questions, you can get help from experienced editors at the Teahouse. We've got a lot of chemistry articles, and I'm always happy to see new editors get involved in that field with content and referencing. Happy editing! DMacks (talk) 16:12, 29 April 2022 (UTC)
