Helium Facts. Helium (He) has two protons in its nucleus, giving the atomic number two. It is the second most abundant element in the universe and is also the second lightest, following behind hydrogen in both cases.
Similarly one may ask, how did the element helium get it’s name?
Helium was first discovered in 1868 by astronomer Pierre Janssen. He noticed the new element when studying a solar eclipse. The element wasn’t found on Earth until 1895. Helium gets its name from the Greek word “helios” meaning “sun”.
What is unique about helium?
Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can explioit these properties. Helium was the first gas used for filling balloons and dirigibles.
What is the element helium used for?
Helium is commercially recovered from natural gas deposits, mostly from Texas, Oklahoma and Kansas. Helium gas is used to inflate blimps, scientific balloons and party balloons. It is used as an inert shield for arc welding, to pressurize the fuel tanks of liquid fueled rockets and in supersonic windtunnels.
Why does helium make your voice?
When you inhale helium, you’re changing the type of gas molecules in your vocal tract and increasing the speed of the sound of your voice. Some people think that helium changes the pitch of your voice, but the vibration frequency of the vocal cords doesn’t change along with the type of gas molecules that surround them.
What does helium do?
Although inhaling helium is fun it’s not exactly healthy. Every time you inhale pure helium, you are not inhaling oxygen. Whatever you do, never inhale helium from a high pressure tank! Besides the serious risk of lung damage, you could end up with bubbles of helium in the arteries that lead to your brain.
How common is helium?
Helium is the second most abundant element in the universe, but here on earth, it’s rather rare. Most people guess that we extract helium from the air, but actually we dig it out of the ground. Helium can be found in certain parts of the world, notably in Texas, as a minor component in some sources of natural gas.
What are some interesting facts about beryllium?
Interesting Beryllium Facts: It is a hard metal, but is brittle at room temperature. Beryllium salts have a sweet taste, and the element was once called glucine with a symbol of Gl due to its flavor. Beryllium has a long history, having been known to the ancient Egyptians in beryl and in emeralds.
How much is it for helium?
The federal government, which sets helium prices, announced in April that helium prices would spike from $75.75 per thousand cubic feet (Mcf) in FY 2012 to $84 per Mcf in FY 2013. (Last year, prices rose only 75 cents.)
Can Helium be toxic?
In those cases, the helium crowds out the oxygen, asphyxiating a person. Death from inhaling helium is so rare that the American Association Poison Control Centers lumps it in with other gases, such as methane and propane. Only three deaths were recorded in 2010, said spokeswoman Loreeta Canton.
What is the color of helium?
Helium is a colorless and odorless gas in its natural state. It gives off a blue neon color when burned. When an electric current runs through it, helium is a pale peach to orange color.
Why is helium used for technological applications?
Helium’s low boiling point makes it a good coolant for magnets in hardware like MRI machines. At minus 452 degrees Fahrenheit, the gas is used to transform the magnets into superconductors that power scanners to create more powerful magnetic fields.
What is the use of helium in our daily life?
Helium is used as an inert shield for arc welding to pressurize the fuel tanks of liquid fueled rockets and in supersonic wind tunnels. The most readily recognized use for helium gas is to inflate blimps, scientific balloons and party balloons.
What are some interesting facts about Argon?
Argon is the third most prevalent gas in the Earth’s atmosphere, found at 9,300 parts per million. It makes up 1.28% of the Earth’s atmosphere. It was the first noble gas to be discovered. Argon is a colorless, odorless, and non-toxic material in all three of its states.
What does the element helium look like?
What does it look, feel, taste, or smell like? Helium is seen on earth as a colorless and odorless gas. It is the clearest element, and even in a liquid state (which can only be achieved by either applying great pressure or extreme cold) it is almost completely transparent.
What are some interesting facts about hydrogen?
It is a nontoxic, odorless, colorless gas that naturally exists in our Universe. Being the first element on the periodic table, Hydrogen is the lightest of all chemical elements. Interesting Hydrogen Facts: Majority of the Universe’s mass (75%) is comprised of Hydrogen.
Why does helium float?
The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the weight of the helium plus the balloon fabric is lighter than the air it displaces, the balloon will float in the air. It turns out that helium is a lot lighter than air.
What are some interesting facts about lithium?
While being the lightest metal under normal conditions, it is still the most dense. With an atomic number of three, lithium has three protons in the nucleus, but like many other alkalai metals it has only one valence electron. Interesting Lithium Facts: It is the least reactive of the alkalai metals.
Can you turn helium into a solid?
Helium is one of only two natural elements that has never been observed bonding to another element in a compound. At normal atmospheric pressure helium does not solidify. At 25 atmospheres of pressure helium is a solid at 0.95 K. As the pressure rises, the temperature at which solid helium exists also rises.
What is the cost of helium?

What does helium react to?
Helium is colorless, odorless, and tasteless. It has a very low boiling point, and is monatomic. Helium is small and extremely light, and is the least reactive of all elements; it does not react with any other elements or ions, so there are no helium-bearing minerals in nature.
Why do we use helium in balloons?
This is because helium is less dense. Because helium is lighter than air, a helium balloon rises. Hydrogen is another gas lighter than air; it is even lighter than helium. Hydrogen is not used in balloons and this demonstration shows why.
What is the temperature of liquid helium?
At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −270 °C (about 4 K or −452.2 °F). Its boiling point and critical point depend on which isotope of helium is present: the common isotope helium-4 or the rare isotope helium-3.
Can you have solid hydrogen?
The squished hydrogen is a precursor to a state of matter first proposed in the 1930s, called atomic solid metallic hydrogen. When cooled to low enough temperatures, hydrogen (which on Earth is usually found as a gas) can become a solid; at high enough pressures, when the element solidifies, it turns into a metal.
