Quizplus · Accepted Answer

The three stable gases in the atmosphere are nitrogen, oxygen, and argon. According to current measurements, nitrogen is the most abundant gas, followed by oxygen and then argon. Carbon dioxide is a variable gas in the atmosphere and its abundance can fluctuate depending on various factors such as human activity and natural processes. Therefore, options A and B are incorrect. Option C has nitrogen as the second most abundant gas, which is not correct. Option D has oxygen as the most abundant gas, which is also not correct. Thus, the best choice is E - nitrogen, oxygen, and argon in order of decreasing abundance.
