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.
Helium is an element with the atomic number two. It has two protons in its nucleus (which is why its atomic number is two), and it comes in two stable isotopes. The most abundâ¦ant one, helium-4, has two neutrons, and helium-3, which has one neutron, is found as only about one atom in a million. 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.
