[edit] Information Sources
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Ruthenium. Additional text was taken directly from the Elements database 20001107 (via dict.org), and WordNet (r) 1.7 (via dict.org). Data for the table were obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but were reformatted and converted into SI units.

[edit] Bad Dot diagram
The dot diagram for this article states that it is in the Noble Gasses group, whereas ruthenium is a transitional metal in the platinum group. —The preceding unsigned comment was added by 63.228.246.132 (talk • contribs) .
- The Lewis structure describes valence electrons and is unrelated to the ground state configuration. Femto 10:36, 30 April 2006 (UTC)
Yes, but ruthenium only has one electron on its outer shell, so it shouldn't have eight dots.--Floyd Elliot 02:52, 4 May 2006 (UTC) [1]
- As a transition metal, it has more than that one available as valence electrons. Femto 10:52, 4 May 2006 (UTC)
[edit] Scarcity
Is ruthenium rare in the universe as a whole, or is it simply rare in the Earth's crust? Does the platinum group concentrate in the Earth's core?--Syd Henderson 03:26, 10 October 2006 (UTC)
[edit] Fission-derived Ruthenium
Are you sure that the activity figures are expressed in Curies? A Curie is HUGE, 1 Ci/gram beign defined as the activity of pure radium! The values quoted appear very far from "safe" to me, even those after 20 years of quarantine time... --159.149.103.4 11:38, 6 November 2006 (UTC)
- A curie is defined as 37 billion disintegrations per second. The curie was originally a comparison of the activity of a sample to the activity of one gram of radium, which at the time was measured as 37 billion disintegrations per second. A radioactive sample that has an activity of 74 billion disintegrations per second, has an activity of 2 curies. When more accurate techniques measured a slightly different activity for radium, the reference to radium was dropped. - http://www.epa.gov/radiation/understand/curies.htm
