Nitrogen makes up about 78% of the mostly homogeneous mixture of gases in Earth's atmosphere. Oxygen is almost 21% and other elements less than 1%.
About 78% of the atmosphere is nitrogen, while 20% is oxygen. Argon makes up less than 1%. Depending on the location, water vapor would be the third or fourth most abundant, comprising up to 4% of the atmosphere.
No, Earth's atmosphere is mostly composed of nitrogen (about 78%) and oxygen (about 21%). Hydrogen makes up a very small fraction of Earth's atmosphere, less than 0.1%.
You must be fishing for "water vapor". It varies a lot (the 'humidity'),but can be up to (not 'at least') about 4%.All other constituents of normal atmosphere are either much more ormuch less than than 4% .
