Hello, I'm Macaddct1984. I noticed that you made a change to an article, Isotopes of lead, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. MacAddct1984 (talk &#124; contribs) 14:52, 9 December 2023 (UTC)
