Molecular size a bit tricky. As a quick comparison, we can use the covalent radius defined as 1/2 the distance between to identical covalently bonding nuclei. This is measured in picometers (1 pm= 1x 10-12 m). Nitrogen's covalent radius is 75pm so the length of a nitrogen (N2) molecule ought to be 4 X 75pm or 300 pm. A molecule of oxygen (O2) ought to be just a shade smaller 4 X 73pm or 292pm. So an oxygen molecule is a little less than 3% smaller than a nitrogen molecule.

This isn't the best response, as it does not take into account the different bonding which is present in the two molecules.
Although one could use covalent radius, it is more appropriate to use a covalent radius determined from similar bonding.
For nitrogen, the covalent radius for a triple bond is 54 pm.
For oxygen, the covalent radius for a double bond is 57 pm.
(Numbers from Wikipedia...)
From these numbers alone, one would expect diatomic nitrogen (with its triple bond) to be smaller than diatomic oxygen (with its double bond).
These numbers are similar to bond lengths for diatomic nitrogen and diatomic oxygen of 110 pm (~2 x 54 pm) and 121 pm (~2 x 57 pm), respectively.

How much do helium balloons carry?
How much a helium balloon carries depends on the size of the balloon.
Are nitrogen molecules Smaller than butane molecule?
Yes, nitrogen molecules are smaller than butane molecules. Nitrogen molecules consist of two nitrogen atoms, while butane molecules consist of four carbon and ten hydrogen atoms. Carbon atoms are slightly smaller than nitrogen atoms, but four of them are definitely larger than two nitrogen atoms, and of course, there are also the ten hydrogen atoms, and although hydrogen atoms are the smallest type of atom, if you have ten of them it does contribute to the size of the molecule. Further to this, the distance between bonds will be smaller in N2 as this is a triple bond because of 3 shared electrons each, whereas it is single bonds between the carbons, elongating the bonds between carbons
Does helium have size?
yes. its covalent radius is 32 pico meter
What are the halogens molecule size?
The size of halogens or the group 17 elements is small.
Why do helium balloons lose air faster than carbon monoxide balloons?
It doesn't literally lose "air," because "air" is not what's inside.But I know what you mean ... you want to know why it losespressure faster, and goes limp and saggy.The molecules of helium are actually physically smaller than the molecules of any component of air, so they escape more readily and more often through the molecular structure of the rubber or mylar skin.(Tentative answer) Helium atoms are smaller than the molecules in air, so they are more likely to pass through the microscopic holes (imperfections) in the latex or mylar. Over time, the net effect is that helium leaves the balloon faster.You are probably referring to the escape of helium, He, from a sealed or knotted balloon.Yes, helium escapes from sealed rubber balloons very much faster than air does. This is because the rubber membrane of a typical toy balloon possesses many small holes or pores, of sizes ranging from smaller than that of a helium atom, to holes thousands of times larger (but still too small to clearly see with the naked eye). He, being the second-smallest atom (next to Hydrogen), passes through many more of these holes than Nitrogen, N, the principal constituent of air and which has an atomic radius many times larger than He. There are other effects at work besides atomic size, but atomic size alone will explain most of the faster deflation seen in He balloons, compared with balloons filled with room air.Helium atoms are smaller than air molecules. The Helium can creep between the rubber molecules in the balloon more easily and quicker than the bigger heavier air molecules.
How does the size of a nitrogen molecule compare to that of propane?
A nitrogen molecule (N2) is smaller than a propane molecule (C3H8). The size of a molecule is determined by its molecular weight and structure. Nitrogen is a diatomic molecule composed of two nitrogen atoms, while propane is a larger molecule composed of three carbon and eight hydrogen atoms.
Does helium have smaller particles than nitrogen or oxygen?
Helium has smaller particles than nitrogen or oxygen. Helium atoms are smaller in size, as they have fewer protons and neutrons in their nucleus compared to nitrogen or oxygen atoms. This smaller size allows helium atoms to move more freely and escape into the atmosphere, which is why helium is a lighter gas.
Is nitrogen dioxide smaller than bromine molecule?
Yes, nitrogen dioxide (NO2) is smaller in size compared to a bromine molecule (Br2). Nitrogen dioxide consists of one nitrogen atom and two oxygen atoms, while a bromine molecule comprises two bromine atoms, making it larger in size.
What nitrogen's atomic size?

This is measured in picometers (1 pm= 1x 10-12 m). Nitrogen's covalent radius is 75pm so the length of a nitrogen (N2) molecule ought to be 4 X 75pm or 300 pm.

What is the atomic radius of helium and how does it compare to other elements in the periodic table?
The atomic radius of helium is about 31 picometers. Helium has one of the smallest atomic radii among all the elements in the periodic table due to its small size and high nuclear charge.
What is the molecule size of air?
Air is a heterogeneous mixture of gaseous molecules and solid particulates. Therefore, there is no single size of an air molecule. Most of air are molecules of nitrogen (N2) and oxygen (O2) gas both of which also have different sizes.
Why in a water molecule is the oxygen atom bigger then the nitrogen atom?
The size of an atom is determined by its electron configuration and the number of electron shells it has. Oxygen has more electron shells than nitrogen, which causes it to be larger in size. Additionally, oxygen has a higher atomic number and more protons in its nucleus, leading to a larger atomic radius compared to nitrogen.
Is helium dence?
depends on the size of its container and volume of helium filling it
What is the atomic size of helium?
The covalent radius of helium is 32 pico meter.
Why do helium balloons reduce in their sizes?
A helium balloon reduces in size because the helium slowly seeps out through the wall of the balloon.
Which element has the greater bond energy Oxygen or Nitrogen?
The bond between nitrogen atoms in an N2 molecule is stronger than the bond between oxygen atoms in an O2 molecule. However, bond energies for the same atom vary with formulas of compounds, so that there is no answer to this question that is correct for every compound of these two elements.
Why does Helium has higher IP than Neon?
because the size of helium is smaller than that of neon.
