Oxygen is the most abundant element in the Earth's crust, making up about 46.6% of its mass.
Silicon
Aluminum is the Earths most abundant metal and its located in the Earths outer crust.One of the properties of crust is that it consists of a variety of sedimentary,metamorphic and igneous rocks.
Oxygen is the most abundant element in Earth's crust, making up about 47% of its mass. Silicon is the second most abundant element, comprising approximately 28% of the crust's mass.
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 main mineral that makes up the Earth's crust is called feldspar. Feldspar is a group of rock-forming minerals that make up about 60% of the Earth's crust by weight.
That element is Oxygen by 46.6%
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.

Silicon
The most abundant element in Earth's crust is oxygen, making up about 46.6% of the crust by weight.
The fifth most abundant element in the Earth's crust is potassium. It makes up about 2.6% of the Earth's crust by weight.
That would be silicon, or SiO2
