Why the size of oxygen gas molecules are smaller than that the nitrogen gas molecules?

The size of an atom is based mainly upon the relative numbers of protons and electrons, and then where the electrons will be located. Since oxygen has one mroe proton than nitrogen, it is more liekly that the electrons in an oxygen atom will be found closer to the nucleus since the strength of the proton pull will be greater.

How would you know from looking at the periodic table that O molecules are smaller than nitrogen molecules?
Oxygen and nitrogen are in the same period of the table, and within a period, atomic radius decreases with increasing atomic number. Oxygen has a higher atomic number than nitrogen. From the periodic table alone, there is no direct information about the size of the molecules, but both these elements form diatomic molecules, and it is reasonable that molecules formed from the same number of atoms will have sizes in the same order as the sizes of the atoms.
Does pure oxygen and pure nitrogen have the same volume?
No. Oxygen and Nitrogen molecules are not the same size. China has a railroad that rides along at 20,000 feet in Tibet. They pump air into the cars. The cars have filters. Nitrogen gas leaves through the filters and oxygen remains in the railroad cars. By using simple pumps and filters they increase the amount of oxygen in the cars. If oxygen and nitrogen were the same size, it would not work.
How many molecules does sulfur trioxide have?
Assuming you meant how many atoms - it has four... 1 Sulphur, and 3 Oxygen.
Which is smaller an element or a molecule?
An atom of an element is usually smaller than a molecule of a compound. Molecules are made by bonding 2 or more atoms, of one or more elements. The molecule is the smallest particle of a compound.
What makes water a excellent solvent?
Water is a good solvent due to its polarity. The single Oxygen molecule and two Hydrogen molecules do not share electrons equally, the Oxygen molecule takes precedent over the Hydrogen molecules. The Polarity and in some small part, the small molecular size makes water the, "Universal Solvent".

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
Why do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?
Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.
Are molecules and X-rays the same size?
No. molecules are smaller.
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.
Is it true that nitrogen is a more reactive element than oxygen?
False, if we look at the general trend of reactivity of the non-metallic elements on the periodic table we see that reactivity is indirectly proportionate to an elements size. A Oxygen is a smaller atom than Nitrogen therefore more reactive.
Two molecules that move across membrane using simple diffusion?
Oxygen and nitrogen can as they are lipid soluble, as well as water molecules due to their small size.
Are all molecules the same size?
No, there is a huge variation in size. DNA and protein molecules are relatively huge. Water and oxygen molecules are quite small. Hydrogen is the smallest.
Do atoms in oxygen double in size?
yes atoms do double in size however atoms in helium are smaller because oxygen atoms double in size.
What nitrogen's atomic size?
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.
How does the distance between the particles in atmospheric air compare to the size of the particles themselves?
Usually in a gas, the distance between molecules is larger.
