What does the name helium mean?
helios
Helium comes from the Greek word for sun, helios. That connection to the sun is the reason why, for nearly three decades after it was first observed, chemists dismissed the element that we use today for everything from filling party balloons to cooling the Large Hadron Collider—and now helium is rapidly diminishing.
What does helium mean in Greek?
The name is derived from the Greek, ‘helios’ meaning sun, as it was in the sun’s corona that helium was first detected.
What does the helium do?
Car/Vehicles: As helium is a very unreactive element, it is used to detect leaks in car air-conditioning systems. It is also used to inflate airbags as helium can diffuse quicker than most unreactive gases.
What is the meaning of hydrogen and helium?
Hydrogen is an element, usually in the form of a gas, that consists of one proton and one electron. Helium is an element, usually in the form of a gas, that consists of a nucleus of two protons and two neutrons surrounded by two electrons.
Where does helium come from on Earth?
On Earth, helium is generated deep underground through the natural radioactive decay of elements such as uranium and thorium. “It takes many, many millennia to make the helium that’s here on the Earth,” says Sophia Hayes, a chemist at Washington University in St.
What is Iron named after?
The Latin name for iron is ferrum, which is the source of its atomic symbol, Fe. The word iron is from an Anglo-Saxon word, iren. The word iron is possibly derived from earlier words meaning “holy metal” because it was used to make the swords used in the Crusades, according to WebElements.

Are helium balloons bad?
Helium is perfectly safe in balloons and safe when balloons are deflated in open and well-ventilated areas but, inhaling it from balloons can be dangerous. Helium displaces oxygen in your lungs when you inhale it, which can cause suffocation and you won’t even realize it.
How long does helium affect your voice?
If you’ve ever breathed helium and heard the sound of your voice, you’ve probably noticed that the effect wears off quickly. That’s because the effect only lasts as long as there’s helium around your vocal cords. As soon as regular air replaces the helium, your voice returns to normal.
What is hydrogen in simple words?
hydrogen (H), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. Under ordinary conditions, hydrogen gas is a loose aggregation of hydrogen molecules, each consisting of a pair of atoms, a diatomic molecule, H2.
Does the Earth need helium?
Helium is the only element on the planet that is a completely nonrenewable resource. On Earth, helium is generated deep underground through the natural radioactive decay of elements such as uranium and thorium.
