Atoms become larger as we go down a column of the Periodic Table, and they becomes smaller as we go across a row of the table.

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.
What gas is present in exhaled?
carbon dioxide
Which has the higher melting point sulfur dioxide or carbon dioxide?
Sulfur dioxide has a higher melting point than carbon dioxide. This is because sulfur dioxide is a smaller molecule with stronger intermolecular forces, making it more difficult to break the bonds in order to melt the substance.
Does oxygen have the highest percentage by volume in dry air than nitrogen carbon dioxide or hydrogen?
No, nitrogen is the most abundant gas in dry air, making up about 78% of the volume. Oxygen is the second most abundant gas, making up about 21% of the volume. Carbon dioxide and hydrogen are present in much smaller amounts.
What gasses are in air?
The main gases in air are nitrogen (about 78%), oxygen (about 21%), and trace amounts of argon, carbon dioxide, and other gases. Nitrogen and oxygen are the most abundant and important components for sustaining life.

Why do nitrogen oxide particles travel faster than bromine particles?
Nitrogen oxide particles travel faster than bromine particles because nitrogen oxides are smaller and lighter molecules, which allow them to move more quickly. Additionally, nitrogen oxides have lower molecular weight and higher temperature compared to bromine, which also contributes to their faster speed.
Does nitrogen dioxide diffuse faster than neon?
No. Gaseous diffusion is a function of mass, with lighter molecules diffusing more rapidly. Neon (approximate atomic mass of 20) is considerably lighter than nitrogen dioxide (approximate molecular mass 46).
Is carbon dioxide a macro molecule?
No, carbon dioxide is not a macromolecule. Macromolecules are large molecules made up of smaller subunits linked together, while carbon dioxide is a small molecule composed of one carbon atom and two oxygen atoms.
What kind of gas does Venus have?
The planet Venus has nitrogen, carbon dioxide and smaller amounts of other gases. Most of the gas is carbon dioxide.
Earth's original atmosphere was made up mainly of water vapor carbon dioxide and .?
The Earth's early atmosphere consisted of Carrbon Dioxide, methane, sulphur, ammonia, nitrogen and smaller amounts (aprox. 0.05%) of other gases.
Are oxygen molecules bigger or smaller then nitrogen molecules?
No CO2 is carbon dioxide, which is a compound consisting of one carbon atom bonded to two oxygen atoms. Carbon dioxide is what you breathe out and what is produced by cars. O2 is simply atmospheric oxygen (what you breathe in). Most oxygen exists as two oxygen atoms bonded together.
Air is made up of 3 gases?
Carbon dioxide, argon, nitrogen,krypton ,neon, xenon ,helium ,oxeygen
Which is smaller in radius bromine or sodium?
Sodium(Na) has smaller radius than Bromine because Na has less number of shells.
What does the atmosphere on Mars is composed mostly of?
95.3% carbon dioxide, 2.7% nitrogen, and 1.6% argon, with smaller amounts of oxygen (0.15%) and water vapor (0.03%).
Why does nitrogen oxide particles travel faster than bromine particles?
Nitrogen oxide (NO) particles travel faster than bromine (Br2) particles primarily due to their lower molecular weight and smaller size. The molecular weight of nitrogen oxide is about 30 g/mol, while bromine has a molecular weight of approximately 160 g/mol. According to Graham's law of effusion, lighter gases diffuse more rapidly than heavier gases, leading to the faster movement of nitrogen oxide particles compared to bromine. Additionally, the kinetic energy of gas particles is influenced by their mass, allowing lighter particles to achieve higher velocities at the same temperature.
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
