Chop suey, (literally âassortment of piecesâ), is as different in contents and style as it appears on different American Chinese restaurant menus. I grew up in the Intermountain West where the Intercontinental Railroad finally hooked the east with the west coasts.
Helium deposits in the earth's crust are thought to have been created by radioctive decay of elements like uranium and thorium. But the largest naturally occuring source of helium is found in natural gas.elium (and the other noble gases that are normally chemically unreactive) are found in volcanic gas emissions. But unless it is really, really large you're not going to be mining it for helium; there just wouldn't be enough to collect there to make it worthwhile.
On Earth it is relatively rare â 5.2 ppm by volume in the atmosphere. Most terrestrial helium present today is created by the natural radioactive decay of heavy radioactive elements (thorium and uranium, although there are other examples), as the alpha particles emitted by such decays consist of helium-4 nuclei.
