Which chemical element represents the most abundant “atoms of an element” found in air?
zalisa [80]

Answer:

The order of elements by volume-fraction (which is approximately molecular mole-fraction) in the atmosphere is nitrogen (78.1%), oxygen (20.9%), argon (0.96%), followed by (in uncertain order) carbon and hydrogen because water vapor and carbon dioxide, which represent most of these two elements in the air, are variable.

I copied and pasted but I hope this information is helpful :)
