Only if it was intentionally or accidentally taken into the atmosphere as part of a space exploration. Usually it's a earth-bound or animal-derived mineral that's too heavy to exist as a "free", airborne element.
Nitrogen and oxygen make up 99% of Earth's atmosphere.
Oxygen accumulates in Earth's atmosphere from photosynthesis, where plants and algae convert carbon dioxide into oxygen. This process started with the emergence of photosynthetic organisms around 2.5 billion years ago, gradually increasing oxygen levels to the current 21 percent.
Nitrogen and oxygen make up about 99% of the Earth's atmosphere. Nitrogen accounts for about 78% and oxygen for about 21%.
Nitrogen is the most abundant gas in Earth's atmosphere, comprising about 78%. Oxygen is the second most abundant, making up around 21%. Other gases like argon, carbon dioxide, and trace gases make up the remaining 1%.
Nitrogen (about 78%) and oxygen (about 21%) make up the largest percentage of Earth's atmosphere.
Nitrogen and oxygen make up 99% of Earth's atmosphere.
The most prominent gases are nitrogen (78 percent), oxygen (21 percent) and argon (nine-tenths of a percent).
Argon and trace gases like neon, helium, and methane make up less than 1 percent of Earth's atmosphere.

Earth's atmosphere makes up a blanket or an envelope around it, which is a mixture of many gases.
No, the earth's atmosphere reflects and absorbs x-rays, so they do not make it to the surface.
They dont they just make the earth hotter
