What is the most abundant element in the Earth’s atmosphere answers com?

By far, the most abundant gas in the Earth’s atmosphere is nitrogen, which accounts for about 78% of the mass of dry air. Oxygen is the next most abundant gas, present at levels of 20 to 21%.

Why nitrogen is the most abundant gas in the atmosphere?

The other primary reason is that, unlike oxygen, nitrogen is very stable in the atmosphere and is not involved to a great extent in chemical reactions that occur there. Thus, over geological time, it has built up in the atmosphere to a much greater extent than oxygen.
