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
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.
The element found in both biotite mica and muscovite mica that makes up the greatest percentage by volume of Earth's crust is oxygen. Oxygen is a very abundant element in the Earth's crust, forming the majority of the minerals and rocks that make up the Earth's surface.
Silicon
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.
after shock
Oxygen is the most common element in the crust.
