The most common element in the Earth's Crust is: Iron 33%
Atmosphere: Oxygen 85%
Ocean: Oxygen 65%
Good Luck, Textbo7
depends if you're talking about in the earths crust, in water or in the human boby. In us, carbon comes second. In the water, hydrogen. In the atmosphere ther is actually way more nitrogen than there is oxygen.
Hydrogen I believe
earths crust , oceans and atmosphere
Oxygen is the most abundant element in the Earth's crust, atmosphere, and oceans. It makes up about 46% of the Earth's crust by weight, about 21% of the atmosphere, and is a key component of water in the oceans.
That element is Oxygen by 46.6%
The Earth's crust contains eight elements. The most common element among the eight is Oxygen (47 percent) and second is Silicon (28 percent).
The rarest element on earth is astatine and it is located in the earths crust. Astatine's availability is said to be less than a gram in weight.
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
Aluminum :D
Yes, argon is found in nature as a trace element primarily in the Earth's atmosphere. It is the most abundant noble gas in the Earth's crust and is produced from the radioactive decay of potassium-40.
Neodymium is relatively abundant in the Earth's crust, with an average concentration of about 38 parts per million. It is considered a relatively common rare-earth element compared to others in the lanthanide series.
Silicon
