diffusion is dependent on chemical reactivity (can't diffuse if you're in a bond)
and mass.
So the lightest most un-reactive gases will diffuse the quickest. Helium would seem to be the best contender. diffusion is dependent on chemical reactivity (can't diffuse if you're in a bond)

What else can I help you with?
Explain the terms STP and NTP And give their values?
STP; 101.3Kpa & 273K (0*C)SATP; 100Kpa, 298K (25*C)
Is helieum a gas?
Not only that, but it's one of lightest, or possibly the lightest, gas in the world. I'm a nerd, so you can trust me.
Is dicarbon dihydride a liquid solid or gas?
This is just a fancy way of saying acetylene which can be a liquid, a solid, or a gas depending on the temperature and pressure it is subjected to. Most often, under STP or RTP, acetylene is a gas.
What is the volume of 3.5mol of CO2 gas at STP?
The volume of gas that 3.5 moles of oxygen occupy can be easily found using the relationship of PV=nRT where P is the pressure, V is the volume, n is the moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin.
How are moles masses or volumes of gases calculated from one another for a gas at STP?
Hey I'm a student too:) it's pretty tricky so don't feel bad if you don't understand. You have a few choices, you can use the ideal gas laws: 1 = (PV)/(nRT) --> and you know at STP (standard temperature and pressure) P = 101.3kPa, and you know T = 0 degrees C = 273K Or you can use knowledge that n = m/M (number of moles = mass/molar mass) V = n x 22.4 (volume = number of moles x 22.4L) n = number of particles / 6.02 x 10^23 Hope this helps:) good luck!
Which period contains the most elements that are all gases at STP?
The noble gases in Group 18 contain elements that are all gases at standard temperature and pressure (STP). Therefore, the period that contains the most elements that are all gases at STP is the third period.
Which 2 elements are gases at STP?
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
What is the most useful thing to know about gases in STP?
Any gas at STP is 0 degrees Celsius and 1 ATM when at 22.414L.
Which halogens are gases at STP?
At standard temperature and pressure (STP), fluorine (F2), chlorine (Cl2), and bromine (Br2) are gases. Iodine (I2) is a solid at STP.
If four balloons are filled with different gases at STP which balloon would go down most quickly the balloon filled with gas CO2 or ch4 or n2 or o2?
The balloon filled with CO2 would go down most quickly at STP because it has the highest molar mass compared to CH4, N2, and O2. The rate at which a gas diffuses or rises is inversely proportional to the square root of its molar mass, so the heavier CO2 gas will descend faster.
What are helium and oxygen?
They are both elements, they are both gases at STP.
What gas would be most ideal if at STP?
Helium comes very close to ideal at STP since it is so small and monatomic. In reality most gases are pretty indistinguishable from ideal at STP because the molecules are so far apart that their individual volumes are negligible compared to the space they are in and the molecules are so far apart that they exert negligible force on each other.
Are the noble gases always in the gas state of matter?
At STP, all noble gases are gases. However, helium can be converted to liquid below-268.93 °C.
Which of the elements in the periodic table are gases at STP?
Among the halogens, fluorine (F) and chlorine (Cl) are gases at STP. In the new, IUPAC approved system, the halogens are placed in group 17. In the two (ambiguous) older systems, their group might be labelled VIIB or VIIA.
What symbol represents a molecule at STP?
The symbol "STP" stands for Standard Temperature and Pressure, which is defined as 0 degrees Celsius and 1 atmosphere pressure. There is no specific symbol that represents a molecule at STP, as STP is a set of specific conditions used for comparing and measuring properties of gases.
What are the particulars of gas in oridanary conditions of temperature and pressure?
the gases behave normally a STP conditions
Is neon a metal semimetal or nonmetal?
ITS A NON METALIt's a gas, one of the so called noble gases because of its reluctance to form compounds with other elements at STP. Other noble gases at STP include helium, argon, krypton, xenon and radon
