SOLAR SYSTEM

Detailed explanation-1: -The most abundant naturally occurring gas is nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%.

Detailed explanation-2: -By volume, the dry air in Earth’s atmosphere is about 78.08 percent nitrogen, 20.95 percent oxygen, and 0.93 percent argon. A brew of trace gases accounts for the other approximately 0.04 percent, including the greenhouse gases carbon dioxide, methane, nitrous oxide and ozone.

Detailed explanation-3: -Q: What physical characteristics do oxygen and nitrogen share? These elements both appear in the same region of the periodic table, making them prefer the gas phase. They liquify at a very low temperature similar to the one at the dark side of the moon and they turn to gas at a strikingly similar boiling point.

Detailed explanation-4: -It might be surprising to find out that the three main greenhouse gases – carbon dioxide, methane and nitrous oxide – comprise just a tiny fraction of Earth’s atmospheric gases. Most of the atmosphere (to a height of 25 km) is composed of just two gases: nitrogen (78%) and oxygen (21%).

Detailed explanation-5: -Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

Detailed explanation-6: -Due to strong triple bond in N2(N≡N) or high activation energy, nitrogen is unreactive and thus is most abundant gas in the Earth’s atmosphere.
