Helium and nitrogen have different properties. Helium is a noble gas that is lighter than air and does not react with other elements. Nitrogen is a non-metal gas that makes up about 78 of Earth's atmosphere and is essential for living organisms. Helium is used in balloons and as a coolant, while nitrogen is used in fertilizers and as a protective gas in food packaging.

What are the differences between the properties of nitrogen and helium?
Nitrogen and helium have different properties. Nitrogen is a gas at room temperature, while helium is a gas at very low temperatures. Nitrogen is a common element in the Earth's atmosphere, while helium is much rarer. Nitrogen is essential for life, while helium is mostly used for balloons and as a coolant in certain applications.
What are the differences between a helium balloon and a hydrogen balloon in terms of their properties and uses?
Helium balloons are safer than hydrogen balloons because helium is non-flammable, while hydrogen is highly flammable. Helium balloons are commonly used for celebrations and decorations, while hydrogen balloons are less common due to safety concerns. Helium is also lighter than air, making helium balloons float, while hydrogen is even lighter but poses a greater risk of combustion.
What is the atomic number of helium and how does it relate to its properties?
The atomic number of helium is 2. This number indicates the number of protons in the nucleus of a helium atom. The atomic number of an element determines its chemical properties, such as its reactivity and bonding behavior. Helium's atomic number of 2 means it has a stable configuration, making it a noble gas with low reactivity and high stability.
What is the difference between helium and air?
Air is another name for Oxygen, the gas we need to breathe in order to survive. Oxygen is an element on the periodic table of elements. Helium is an unreactive element that is even lighter than normal air. It is used commanly in party balloons, inflating huge objects, etc. But the masses are way different. All you need to know that helium is lighter than the air around us.
What are the differences between a hydrogen balloon and a helium balloon in terms of safety, buoyancy, and availability?
Hydrogen balloons are more flammable and pose a higher safety risk compared to helium balloons, which are non-flammable. Helium balloons have better buoyancy and can lift heavier loads than hydrogen balloons. Helium is more readily available and safer to use compared to hydrogen, which is more difficult to obtain and handle safely.
What are the differences between the properties of nitrogen and helium?
Nitrogen and helium have different properties. Nitrogen is a gas at room temperature, while helium is a gas at very low temperatures. Nitrogen is a common element in the Earth's atmosphere, while helium is much rarer. Nitrogen is essential for life, while helium is mostly used for balloons and as a coolant in certain applications.
Why is there nitrogen in helium?
Um... because the helium was insufficiently purified? There is no nitrogen in pure helium.
What element has the least similar properties to nitrogen?
Of the elements, helium has the least similar properties to nitrogen. Helium is a noble gas found in Group 18 of the periodic table and is colorless, odorless, and non-reactive. In contrast, nitrogen is a non-metal found in Group 15 and can form various compounds due to its ability to bond with other elements.
What is the chemical formulas for helium and nitrogen?
The chemical formula for helium is He, while the chemical formula for nitrogen is N₂.
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.
What is helium nitrogen?
Helium is a noble gas with atomic number 2 and is chemically inert. Nitrogen is a diatomic gas with atomic number 7 that is often used in various industrial applications. Mixing helium and nitrogen together can alter the physical properties of the resulting gas mixture, such as density and thermal conductivity, making it useful in specific applications like diving or certain welding processes.
What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
What are the chemical properties for helium?
helium is chemically inert and has no chemical properties
Which one has fewer protons Nitrogen or Helium?
The periodic table is a good reference - check out the atomic number ! Helium - 2 protons, Nitrogen - 7 protons
What are some differences between earth and saturn?
saturn is much bigger than earth. earth has people living on it and saturn doesn't. saturn is made up of hydrogen and helium. earth is made up of oxygen and nitrogen
What are the chemical properties of helium?
Helium is inert. There are no known compounds. It has no chemical properties.
