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.

Which gas diffuses faster carbon monoxide or carbon dioxide?
CO diffuses faster than CO2 because it is a smaller molecule
What gasses are in air?
There are lots of different gases in the atmosphere, but most of the air around is made up of Nitrogen, Oxygen, and Argon. There are smaller amounts of Carbon Dioxide and Water Vapor as well.
Why is ammonia considered a polar molecule?
Ammonia is a polar molecule because the different electronegativity's of the nitrogen and the hydrogen molecules makes the hydrogen slightly positive and the nitrogen slightly negative. However there are 2 valance electons of the nitrogen atom which are not bonded to anything, which are called lone pairs. The lone pairs means that the ammonia molecule is not symmetrical therefore the electronegativity's do not cancel eachother, creating a polar molecule. ( The reason why the shape is no longer symmetircal is because lone pairs repel more than the bond pairs of the N-H, and essentially the bonding pairs are "squeezed" together, which accounts for the smaller than expected bond angle of 107 degrees)
How does nitrogen separate to be useful?
Nitrogen is an element, it does not separate smaller than nitrogen atoms, unless you consider subatomic particles to be useful,
What is smaller a molecule or a micron?
The units are incompatible. Millimetres are linear, micro-litres are for volume.
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.
Air is made up of 3 gases?
Carbon dioxide, argon, nitrogen,krypton ,neon, xenon ,helium ,oxeygen
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.
Which is smaller in radius bromine or sodium?
Sodium(Na) has smaller radius than Bromine because Na has less number of shells.
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
Is a cell smaller than a water molecule?
a cell is much bigger than a water molecule
Which element has a smaller atomic radius bromine or gold?
The atomic radius of bromine is lower.
Which gas diffuses faster carbon monoxide or carbon dioxide?
CO diffuses faster than CO2 because it is a smaller molecule
What are the most common gases?
The most common gases are the nitrogen and oxygen. A dry air is composed of about 21% of oxygen and 78% nitrogen. There is also Argon and carbon dioxide which are present in smaller amounts.
What is molecule consisting of one carbon atom and two oxygen atoms is correctly written as?
C20The two is smaller about half the size of the lettersCarbon DiOxide
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.
