Welcome
Hello, and welcome to Wikipedia!

Someone using this IP address,, removed content from the page Noble gas without giving an explanation. Please always provide an informative edit summary when removing content from pages. If is a shared IP address and you did not do this, you may wish to consider [ getting a username] to avoid confusion with other editors and further irrelevant notices.

Here are a few good links for newcomers:
 * The five pillars of Wikipedia
 * How to edit a page
 * Tips on starting your first article
 * Help pages
 * Tutorial

Here are some other hints and tips:
 * I recommend that you get a username. You don't have to log in to read or edit articles on Wikipedia, but  [ creating an account]  is quick, free and non-intrusive, requires no personal information, and there are many benefits of having a username. (If you edit without a username, your IP address is used to identify you instead.)
 * When using talk pages, please sign your name at the end of your messages by typing four tildes . This will automatically produce your username (or IP address) and the date.

I hope you enjoy editing here and being a Wikipedian! If you need help, check out Where to ask a question, ask me on my talk page, or type  here on your talk page and someone will show up shortly to answer your questions. Again, welcome! David Brooks (talk) 03:38, 5 March 2019 (UTC)
