no. If it was, we would have oxygen balloons instead of helium balloons.

Oxygen is heavier than helium. Oxygen has an Atomic Mass of around 16 g/mol, while helium has an atomic mass of around 4 g/mol. This means that oxygen molecules are heavier than helium molecules.

Why is helium heavier than air?
Helium is lighter than air because of atomic mass. Helium is element number two, whereas oxygen is element number 8. Oxygen has an atomic mass of 16, and helium has a mass of 4, so helium is 4 times lighter than air. (Atomic mass is the total mass of protons, neutrons, and electrons in a single atom.)
How does density of helium compare to density of oxygen and nitrogen?
Helium is less dense than oxygen and nitrogen. It is about 7-8 times less dense than air, which is a mixture of nitrogen and oxygen.
Why does helium float?
Helium floats because it is lighter than the surrounding air. Its density is lower than the density of the air, causing it to rise. This buoyancy effect is what causes helium balloons to float.
Is helium light or heavy?
Helium is classified as a light element because it has a low atomic mass compared to other elements like oxygen or iron. It is lighter than air, which is why helium-filled balloons float.
Which is lighter oxygen helium or nitrogen?
Helium is the lightest of the three gases, with an atomic mass of 4 compared to 16 for oxygen and 14 for nitrogen.
How does density of helium compare to density of oxygen and nitrogen?
Helium is less dense than oxygen and nitrogen. It is about 7-8 times less dense than air, which is a mixture of nitrogen and oxygen.
Why can helium escape the earth's atmosphere?
Helium is lighter than oxygen and can escape the ozone.
Which is lighter oxygen helium or nitrogen?
Helium is the lightest of the three gases, with an atomic mass of 4 compared to 16 for oxygen and 14 for nitrogen.
Is there anything lighter than oxygen?
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
How much faster does helium diffuse than oxygen?
Not much faster, but it does diffuse faster than helium because it is lighter.
Why is helium heavier than air?
Helium is lighter than air because of atomic mass. Helium is element number two, whereas oxygen is element number 8. Oxygen has an atomic mass of 16, and helium has a mass of 4, so helium is 4 times lighter than air. (Atomic mass is the total mass of protons, neutrons, and electrons in a single atom.)

Is helium lighter or heavier?
Helium is lighter than air
Which is lighter - helium or hydrogen?
Helium is lighter than hydrogen. Helium has an atomic number of 2, which means it has two protons and two neutrons in its nucleus, making it lighter than hydrogen, which has only one proton in its nucleus.
Why is helium lighter than CO2?
Helium is lighter than CO2 because it has a lower atomic mass. Helium is made up of two protons and two neutrons, while CO2 is made up of one carbon atom and two oxygen atoms. The overall molecular weight of helium is much lower than that of CO2, making it lighter.
Why is helium used in airships rather than oxygen?
Helium is a lighter gas than oxygen, ever seen balloons filled with helium? They rise upwards with heat due to a lesser amount of particles. If we used oxygen, the airships wouldn't get off the ground!
Is helium or hydrogen lighter than oxygen?
YES ! see periodic table for more info
