It was nominated for the 2010 British Academy Television Awards in the category Specialist Factual. Only in the last 200 years have we known what an element is – a substance that cannot be broken down further by chemical reaction.

Atmospheric Chemistry and Physics publication process. In the first stage, papers that pass a rapid access peer-review are immediately published on the "Atmospheric Chemistry and Physics Discussions" forum website. They are then subject to interactive public peer review, including the referees' comments (anonymous or attributed), additional comments by other members of the scientific community (attributed), and the authors' replies. In the second stage, if accepted, the final revised papers are published in the journal. To ensure publication precedence for authors, and to provide a lasting record of the scientific discussion, both the journal and the forum are permanently archived and fully citable. This journal
