Welcome!

Hello, and welcome to Wikipedia!

Someone using this IP address, 208.102.2.121, has made edits that do not conform to our policies and therefore have been reverted. The recent edits, although made in good faith, caused the articles to deviate from our Manual of Style. If you did not do this, you may wish to consider getting a username to avoid confusion with other editors. If you'd like to experiment with the syntax, please do so in the sandbox rather than in articles.

You don't have to log in to read or edit pages on Wikipedia, but creating an account is quick, free, requires no personal information, and has many benefits. Without a username, your IP address is used to identify you.

Some good links for newcomers are:

• Help contents – the main help page.
• Quick guide – a "cheatsheet" listing the main editing commands.
• The five pillars of Wikipedia
• Contributing to Wikipedia
• Tutorial

Please sign your name on talk pages using four tildes (~~~~); this will automatically produce your name and a timestamp. If you need help, check out Wikipedia:Questions, ask the Help Desk, or place {{helpme}} on your talk page and someone will show up shortly to answer your questions.

Welcome to Wikipedia, and thank you for your contributions. Although everyone is welcome to contribute constructively to the encyclopedia, please note that there is a Manual of Style that should be followed to maintain a consistent, encyclopedic appearance. Deviating from this style, as you did in Isotopes of hydrogen, disturbs uniformity among articles and may cause readability or accessibility problems. Please take a look at the welcome page to learn more about contributing to this encyclopedia. In this case, you may wish to read the style guidelines for formatting of numbers. Thank you.
