[edit] Huh?
"Hassium-270, a doubly magic isotope"
That has 108 protons and 162 neutrons. The magic numbers on the linked page are 2, 8, 20, 28, 50, 82, 126. 108 and 162 are not in the list. Ken Arromdee 08:45, 28 December 2006 (UTC)
- Hehe, I was just about to say something similar, but you beat me to it. Another article on Wikipedia leads me to the same conclusion. --DachannienTalkContrib 08:49, 28 December 2006 (UTC)

- Actually, i've just completed a course on applications of radioactive ion beams. Magic numbers aren't fixed when you're approaching the Neutron-rich & Proton-rich drip lines (theoretical limit of how many neutrons you can squeeze in a atom with fixed number of proton, and vice-versa). The classic magic numbers we see are based on stable elements and extrapolated for them. Things get really strange once you get near the drip lines: some magic numbers vanishes, new ones appear. Since I don't have my notes in front of me, I'm guessing this is what happening with Hassium-270. 154.20.57.153 04:29, 29 December 2006 (UTC)

[edit] chemical and physical properties
I've deleted the following text, which does not cite a source. If we really want to print speculation, we at least need a source for why this speculation might make sense.
- It is predicted that hassium will be the densest element yet known, with a density exceeding two and a half times that of lead. This assumes that a measurable quantity of the element can be made, which is not possible at this time.

- I've reverted another edit about the density, which also does not a cite a source. Specifically, the text "estimated 41 g/cm³" in the elementbox and "Hassium is probably the densest element known, with an estimated density of 41 g/cm³." in the article (the latter was also poorly placed - next to the ref tag for the "Chemistry of Hassium" paper, although I saw no mention of density in that paper). If there is a reason to include this in the article, we need a source for the information. See WP:ATT for example. Kingdon 00:08, 21 February 2007 (UTC)
