Isotopic mas of hydrogen ia '1'
Isotopic mass of nitrogen is '14'
Isotopic mass of oxygen is '16'
It follows that oxygen is the n=heaviest of these gases.

It is nitrogen, followed by oxygen.
nitrogen gas and hydrogen gas
Nitrogen and hydrogen react to form ammonia. This is the reaction in the Haber process, in which the gases are mixed at high pressure and moderately high temperature and passed over an iron catalyst.
Nitrogen (and oxygen and hydrogen) in the form of a gas is usually found as a molecule of two atoms of Nitrogen. That is N2. The fairly weak bond can be broken chemically, by heat, etc, and then you would have N.
Substances that exist in the gaseous phase are commonly referred to as gases. The most common example of a gas is air (the air we breathe is a gas). It can also be considered as a mixture of many gases such as nitrogen, oxygen, and carbon dioxide.
It is nitrogen, followed by oxygen.
oxygen nitrogen neon carbon dioxide hydrogen Argon, neon, hydrogen, oxygen and nitrogen are gasses.
Hydrogen
Cheese right someone put cheese how is that a colourless gas i will never know but i think the answer is gas
Helium gas, and trace amounts of Oxygen and Nitrogen.
O2 - oxygen gas H2 - Hydrogen gas N2 - Nitrogen gas
