Life on Earth is carbon-based. Carbon forms bonds with hydrogen and oxygen to create organic compounds.
It is also often said that all life depends on water, meaning that all life requires the hydrogen and oxygen atoms too.
CARBON!
Hydrogen
metal is it family and rare earth element is used if you do not know the family property
No. Earth's atmosphere is a mixture, mostly comprised of nitrogen and oxygen.
None. The alkaline earth metal isotope with the fewest neutrons would be beryllium-7 with three neutrons and a half-life of 53 days.
Astatine is the rarest naturally occuring element on Earth because all its isotopes are radioactive with very short half-lives. The most stable, At-210 has a half-life of 8 hours, so any astatine that forms (by radioactive decay of heavier elements) quickly decays to other elements.

Carbon. Life on Earth is based on the complex chemistry of Carbon.

Water is not an element. The element that is most present in the atmosphere is Nitrogen at about 70% (Oxygen is about 20%). I don't know about the most common element in the earth's crust though. I'd say that the most common element overall is Carbon (since all life is carbon based)
no its not bcuz aug is a precious metal and earth does not have metal in its inner core aquafier and or the mantle so thre u have it gold is not an earth based element ;D

No there's earth, wind, water, and fire.
