Nitrogen is the least abundant element in the atmosphere of the Earth. The most abundant element in the atmosphere of the Earth is oxygen.
I suppose that you think to minor noble gases.
The least expensive thing on earth is typically air, which is freely available in the atmosphere and does not have a monetary cost associated with it.
No, the atmosphere is not the densest layer of the Earth. The densest layer is the inner core, which is a solid ball of iron and nickel at the center of the Earth. The atmosphere is a relatively thin layer of gases surrounding the Earth.
Plutonium is least likely to have been a component of Earth as it is a man-made element that is not naturally occurring in significant quantities.
Nitrogen is the most abundant gas in Earth's atmosphere, followed by oxygen, argon, and carbon dioxide.
that sounds unanswerable.
Beryllium is the alkaline earth element with the least massive atoms.
The exosphere is the least dense part of the earth's atmosphere.
Plasma is the least common phase of matter on Earth. It requires very high temperatures to exist, so naturally occurring plasmas on Earth are relatively rare compared to solids, liquids, and gases. Examples of plasma on Earth include lightning, the sun's atmosphere, and some types of flames.
No.
At 0.3%, carbon dioxide is the least common gas in the Earth's atmosphere. This is in no way indicative of its lack of importance, since carbon dioxide is the primary source of life on earth and its concentration on earth's pre-industrial atmosphere has been regulated by photosynthetic organisms and is a principle supplier of greenhouse gases.
I suppose that you think to minor noble gases.
Everywhere, at least on earth and in the earths atmosphere.
Argon at about 1%
the Earth has 3 main layers the Atmosphere, Crust, and Mantle/Core the Atmosphere is made up of mostly gas the Crust is made up of (mostly) solids and the Mantle/Core is filled mainly with liquid metals
Gases like helium can escape Earth's atmosphere because they have low molecular weight, which allows them to reach escape velocity more easily. Additionally, helium is light enough to be carried away by solar winds, contributing to its escape from the atmosphere.
