The second issue of Food Security is now published, and is free online. It documents some of the multiple causes of food insecurity.
Helium can be found in underground deposits in the earth. Helium can also be found in stars and other planets. The helium underground - and extracted from natural-gas - is a by-product of the natural radioactive decay of uranium, though is far too stable to be radioactive itself. It also occurs in very small amounts in the atmosphere.
The element helium is an inert or noble gas, and is found on the periodic table with the other inert gases in Group 18. They're the elements down the far right column of the table. Helium, which is the second most abundant element in the universe (behind hydrogen) is about a quarter of all matter.It is a gas here on earth, and can only be liquefied if it is cooled to near absolute zero. It will not solidify, by the way. Outside earth, it is mostly found in stars where it is a plasma.We know that helium, which is colorless, odorless and tasteless, does not want to chemically combine with any other atoms. It has a valence of zero, and it is found on earth as a monatomic gas, hanging around as single atoms.elium, which is the second most abundant element in the universe (behind hydrogen) is about a quarter of all matter. It is a gas here on earth, and can only be liquefied if it is cooled to near absolute zero. It will not solidify, by the way.
