Hello, I'm JohnBlackburne. I wanted to let you know that I removed one or more external links you added to the page Hydrogen atom, because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.
