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.
Oxygen is the most abundant element in the earth's crust and is not in the boron family. Aluminum is in the boron family and is the third most abundant element in the earth's crust. Refer to the related link for a list of the 10 most abundant elements in the earth's crust and their percentages.
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.
