Hello, I'm ComplexRational. I noticed that you added or changed content in an article, Tantalum, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources, or if you think I made a mistake, you can leave me a message on my talk page. ''Also, keep in mind that fictional uses normally aren't discussed in main articles, as they often fall out of scope and digress. If this use is significant and covered in reliable sources, it may be appropriate to add to Materials science in science fiction or a related article.''
