Helium can be found all over the universe, although it isn't widely distributed on Earth. Its most frequent form is gas. It shares many characteristics with other noble gases. Helium doesn't form compounds easily with other elements. It is also very stable. But as the facts earlier show, the element is very usable.

An Element of Interest The simple answer is that helium is both chemically inert and extremely light. Its inertness ensures that it rarely gets trapped in compounds, while its lightness means that as soon as it is released into the air it floats off into space. And space is where the gas was first found.

Those orange stars found to have a higher than usual concentration of lithium (such as Centaurus X-4) orbit massive objects—neutron stars or black holes—whose gravity evidently pulls heavier lithium to the surface of a hydrogen-helium star, causing more lithium to be observed.

Once all the hydrogen in the core has been used up, helium is fused into carbon, nitrogen and oxygen. This causes the core to expand and cool once again. The shell, which is still fusing hydrogen, also cools. When all the helium has been used, the core contracts and warms. This heats up the shell which now starts fusing helium.

Amazing that Helium doesn't allow you to backup to an external sd card, or to a local (lan) drive. Maybe this is a feature of the full (paid for) version of Helium..? Logically it doesn't make sense to back up to your local internal storage because (as you say) you're likely about to reset the phone.

Beryllium is found in beryl and emerald, minerals that were known to the ancient Egyptians. Although it had long been suspected that the two minerals were similar, chemical confirmation of this did not occur until the late 18th century. The beryllium atom is analogous to helium in that both atoms have two outer electrons, but the atom is

He thought that it was caused by an element that was not found on the earth. Sir William Ramsay was the first to isolate helium. In March, 1895, he treated the mineral cleveite with mineral acids and, when he analyzed the mixture, discovered a yellow line in the emission spectrum.

Helium is a strategic industrial mineral element of which the occurrence on earth is relatively rare. It has become an increasingly important substance with the advent of super conductors (especially for MRI machines) and is needed for inert gas flooding during conductive metals welding and in the manufacture of silicon and germanium crystals and wafers.

The star makes helium by squashing four hydrogen atoms together into one new helium atom. So stars are made mainly of hydrogen and helium atoms. When a star runs out of hydrogen, it begins to turn helium atoms into carbon atoms instead.

French astronomer Pierre Jules Csar Janssen camped out in Guntoor, India, to watch as the moon passed in front of the sun and revealed the solar prominences. Like other sun-gazers that morning, Janssen discovered that the prominences were mostly made of super-hot hydrogen gas.

Helium-3 is a stable isotope of helium containing 2 protons and 1 neutron. He-3 accounts for 1.37 x 10-4 % of helium found in the atmosphere. 4 He Helium-4 is also stable with 2 protons and 2 neutrons. It is the most common form of helium found. It's abundance in the atmosphere is 99.999863% of all helium found.
