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.
In very hot stars, helium can be ionised so we can expect to see spectral lines due to absorption by helium ions. In most stars the temperature is too cool for helium to ionise so no such lines can form in the spectrum. Even though spectral lines due to helium are not found in cool stars it does not mean that helium is missing from the star. In fact helium is the second most abundant element in the Universe and in stars.
