What else can I help you with?
Is helium lighter than nitrogen?
Yes, helium is lighter than nitrogen. Helium is the second lightest element, while nitrogen is a bit heavier due to its molecular structure. In fact, helium is the lightest noble gas and is commonly used in balloons for this reason.
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
What would happen if you poured liquid helium into liquid nitrogen?
If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the nitrogen.
How many times heavier is a sulfur atom than a helium atom?
A sulfur atom is about 32 times heavier than a helium atom. This is based on the atomic masses of sulfur (32 amu) and helium (4 amu).
What is nitrogen fusion?
Nitrogen fusion is a nuclear reaction in which nitrogen atoms combine to form heavier elements, such as helium or carbon. This process occurs in the cores of massive stars during their later stages of evolution and is part of the sequence of reactions that produce the energy necessary to keep the star shining.
Is helium lighter than nitrogen?
Yes, helium is lighter than nitrogen. Helium is the second lightest element, while nitrogen is a bit heavier due to its molecular structure. In fact, helium is the lightest noble gas and is commonly used in balloons for this reason.
How are the elements carbon nitrogen and oxygen produced in stars like the sun?
These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
In the cores of stars nuclear reactions convert helium to?
In the cores of stars, nuclear reactions convert helium to heavier elements like carbon, oxygen, and nitrogen through processes like fusion. This conversion of helium to heavier elements releases energy and is essential for the life cycle of stars.
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
Why is there nitrogen in helium?
Um... because the helium was insufficiently purified? There is no nitrogen in pure helium.
How does density of helium compare to the density of oxygen and nitrogen?
Helium is less dense than oxygen and nitrogen. Helium is the second lightest and least dense gas, while oxygen and nitrogen are heavier gases. This is why helium is often used to lift balloons, as it is less dense than the surrounding air.
What is the chemical formulas for helium and nitrogen?
The chemical formula for helium is He, while the chemical formula for nitrogen is Nā.
What makes the balloon rises?
Helium gas in the balloon causes it to rise as it is much less dense than the surrounding air which has heavier molecules such as Oxygen, Nitrogen, Carbon Dioxide, etc.
What are two atoms that are heavier than carbon?
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
What nuclear process coverts helium and hydrogen gases from lighter to heavier elements?
The process is called fusion; hydrogen nuclei are fused together to make helium. At much higher temperatures and pressures, the helium can fuse into carbon and nitrogen and oxygen.
Is nitrogen and helium a hot gas?
yes helium and nitrogen are hot gases
What would happen if you poured liquid helium into liquid nitrogen?
If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the nitrogen.
