Arsenic edit

"The toxicity of beryllium is on par with other toxic metals, such as arsenic and mercury" --> Arsenic is not a metal.Eudialytos (talk) 22:00, 6 May 2021 (UTC)Reply

Changed article to read "metalloids/metals" since few would consider arsenic a metal. The current arsenic wiki page identifies arsenic as a metalloid. I agree there is no precise definition of "metalloid." Rdevany (talk) 02:19, 3 December 2022 (UTC)Reply
Exactly. Thanks!Eudialytos (talk) 23:19, 18 May 2023 (UTC)Reply
IUPAC?
In the periodic table there are metals, non-metals, and semimetals. Arsenic belongs to the last group.Eudialytos (talk) 23:18, 18 May 2023 (UTC)Reply

Beryllium is produced by fusion of Lithium and Hydrogen in the Sun edit

There is no other explaination for the trace amounts of 7Be with a half life of little more than 50 days. 178.202.60.40 (talk) 08:58, 23 April 2023 (UTC)Reply

That is incorrect. " 7Be: a promising short-term soil tracer: Beryllium-7 is a natural cosmogenic radionuclide produced in the upper atmosphere by cosmic ray spallation of nitrogen and oxygen. Seasonal variations in the 7Be concentration in the lower atmosphere have been observed and have often been attributed to the influence of variations in the rate of exchange of air between the stratosphere and the troposphere (Feely et al., 1989). This radionuclide has a very short half life (t1/2 = 53.3 days) relative to 137Cs and 210Pb, which means that it offers....." [1]. Plantsurfer 10:10, 23 April 2023 (UTC)Reply

Beryllium-8 natural occurrence edit

Shouldn't beryllium-8 be listed as "intermediate " rather than "synthetic", since it's in secular equilibrium in helium fusing stars such as the sun? 174.103.211.189 (talk) 04:16, 7 December 2023 (UTC)Reply
