Speed of sound in beryllium is probably a record for solids, and I have a reference for the 12870 m/sec in thin rods at r.t. (room temp). I have no idea where the other value given is from, or what the n means. So I've deleted it. [1] S B H arris 02:53, 19 December 2007 (UTC) reply

Beryllium in the +III oxidation state is a rather extraordinary claim, given the size of the third ionization potential. The citation given (which directs the reader to J. Food Chem. 1994, 50, 91-93) gives no structure of this purported complex, nor is it clear which (if any) of the reference given therein contains it. Stronger evidence than this is needed to say that a +III state exists. My feeling is that it is a rather egregious typo in the journal article. Ymwang42 ( talk) 20:00, 1 January 2010 (UTC) reply

Yall had the heat of fusion wrong, I changed it for yah.

Someone prolly thought it needed to be converted from mol to g when it was already in the correct unit —Preceding unsigned comment added by 168.103.182.177 ( talk) 07:35, 20 January 2010 (UTC) reply
