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.
What else can I help you with?
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.
Which element has a smaller atomic radius bromine or gold?
The atomic radius of bromine is lower.
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%).
What gas is present in exhaled?
carbon dioxide
