Why do they need to have 4 electrons in the outershell???? Where do the other two electrons go? Maybe to another universe or dimension????? — Preceding unsigned comment added by 2001:569:7CB9:EC00:BCBB:4517:B01A:8387 ( talk) 20:16, 13 January 2024 (UTC)
In building an aluminium vessels is lead sheeting a good idea to use directly on aluminium. There is no seawater where it is being used. Its purpose is to protect electrical cables from aluminium sharp edges. Is this good practice. 83.211.151.105 10:23, 12 December 2006 (UTC)
I have removed the following text from the article because it is so poorly written and formatted that it detracts from the article rather than improving it. -- Ed ( Edgar181) 19:30, 26 November 2012 (UTC)

I have raised my concerns at Wikipedia talk:WikiProject Chemistry#The term crystallogens for group 14: a case of citogenesis?, Wikipedia talk:WikiProject Elements#Is crystallogen a case of citogenesis?, and Wikipedia talk:List of citogenesis incidents#Crystallogens. I unfortunately must number myself among those who assumed too much good faith or simply assumed there were references they could not access along the way and now have egg on their faces; at least the situation here isn't as bad as on French Wikipedia, where the article is still at Cristallogène, which seems to be just as non-standard in French.

Flerovium wouldn't necessarily be toxic based on radioactivity. Those are 2 different things. For example, bismuth is radioactive (more than a billion times the age of the universe) and is not significantly toxic. Lead is considerably toxic, sure no one disputes that, but radioactivity doesn't make it toxic. 74.135.194.87 ( talk) 04:11, 18 February 2024 (UTC)
