Float High With Helium
ARE YOU GOING TO A BLEAK, FARAWAY PLANET? DO YOU WANT TO SURVIVE? OR BETTER YET, DO YOU WANT TO LIVE IN COMFORT? THEN BRING HELIUM!
What is Helium?
and its properties
Helium was discovered in 1895 by Norman Lockyer and Pierre Jules Cesar Janssen. Its name comes from the Greek word Helios which means sun. Helium is an odorless, tasteless, colorless, and nontoxic element. The symbol for Helium is He. The atomic number is 2, the atomic mass is 4.00260, and the mass number is 4. It is located in group 18 and period 1. It's a noble gas and will not bond with any other elements. This makes it a very safe, nonreactive, and nonflammable element. Helium has 2 protons, 2 neutrons, and 2 electrons. Helium usually exists as a gas, but liquid Helium is one of the coldest substance on Earth, and it's a very useful coolant. It has extremely low boiling and melting temperatures. The boiling point is -452.1°F (-268.9°C), and the melting point is -458°F (-272.2°C). Helium also has a density of 0.1785 g/ cm3, which makes it lighter than air.
So why Helium?
Helium is a very important element, essential to living successfully. Helium has many uses and it would be in your best interests to pack it with you. The most common use of Helium is in party balloons, but its can be used for so much more that that. For instance, fiber optic cables, which are used to bring internet and cable television to people's homes need Helium to be created. Helium is also very important for MRI scans, which doctors use to diagnose tumors, cancers, heart issues, and brain diseases. Furthermore, Helium can be used to cool down some thermo-graphic cameras, which can be used by rescue squads to find people in the midst of smoke or rubble (cooled cameras are more sensitive). In addition, military submarine detectors use liquid Helium to help clear up signals. Some other uses of Helium include, blimps and hot air balloons, deep sea diving, finding gas leaks in products such as fire extinguishers, air conditioners, tires, and aerosol products, producing extremely powerful magnets, and when combined with neon, it can become a helium-neon laser, which is used in laser eye surgery.
Where can you find Helium?
Helium is one of the rarest elements on Earth. In fact, Helium is only 0.00052% of Earth's atmosphere. Most Helium comes from underground. It is formed when the atoms of radioactive elements like uranium start to decay. Helium is most abundant in radioactive places. A lot of Helium can be found in the United States.
- I only gave biological need one star because Helium isn't necessary for a body to physically survive.
- I gave social need four stars because Helium is used in the making of a lot of products that can be traded and bartered for other supplies. (ex: fiber optic cables, balloons, and magnets)
- I gave functional need three stars because Helium can be used in the making of a lot of advanced and everyday products that can be used by you, if you chose to bring Helium. (ex: helium-neon lasers, detecting gas leaks in everyday products, and MRI scanners)
- I only gave defensive need one star because you can't really make anything with Helium that you can protect yourself with.
