Talk:List of elements by density/Numeric densities

From Wikipedia, the free encyclopedia

Here's a sample of what I want to do... I might have mixed up some of the elements (although I doubt so) but what didn't work was the sort template... I'm guessing it only accepts two digits. isn't there a better way to work a WP table?... I just pasted my entries one by one...

This is a list of the chemical elements, sorted by density measured at standard temperature and pressure. (The first elements from hydrogen to radon are gases at normal room temperatures.)
