What else can I help you with?
Is helium expensive?
Yes, helium is considered to be expensive. It is a finite resource and its production and supply are limited. The cost of helium has been increasing in recent years due to the growing demand and limited availability, which makes it relatively expensive compared to other gases.
Why helium weak?
Helium is considered weak because it has a low boiling point and low density which makes it less effective at interacting with other substances. This leads to its inert nature in terms of chemical reactivity and makes it difficult to form stable compounds.
Percentage of abundance of helium in atmosphere?
Helium makes up about 0.0005% of the Earth's atmosphere, making it relatively scarce compared to other gases like nitrogen and oxygen.
What element that is considered unreactive because it has a filled outer energy level is?
Helium is considered unreactive because it has a filled outer energy level with two electrons in its 1s orbital. This makes it very stable and unlikely to form chemical bonds with other elements.
Why is helium used for balloons?
Helium is used for balloons because it is lighter than air, which allows the balloon to float. This makes it a safe and effective choice for creating floating balloons for parties and events.
Is there helium in airships?
Yes. Helium isn't flammable, which makes it the safer option.
Where can helium be found in your house?
Helium makes up about 0.0005% of the earth's atmosphere.
What does helium have in it that makes it float?
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
What makes a helium balloon fly?
A balloon filled with helium flies because helium weighs less than air.
Does sun burns helium to make hydrogen?
no it has hydogen and helium but it makes heat and light
What percentage of helium is in the sun?
Helium makes up about 24% of the sun's mass.
What property of helium makes it an important component of welding systems?
Helium is an inert gas.
What makes a party balloon float?
Helium!
What property of the gas helium makes it useful in balloons?
Helium is lighter than air, which allows balloons filled with helium to float. Its low density also makes it safe for use in air-filled spaces.
What is helium and What is its use for?
its the 2nd element on the periodic table and it makes things lighter, such as helium balloons, which float as helium is lighter than air
Why helium is an element?
Helium is an element because it contains only one atom in its simplest form.
What two main gases are found in the sun?
The two main gases found in the Sun are hydrogen and helium. Hydrogen makes up about 74% of the Sun's mass, while helium makes up about 24%.
