The Most Abundant Elements In The Earth's Crust. The Earth's crust is of two types, the continental crust and the oceanic crust. read more
Oxygen is the most abundant element in the Earth's crust. Oxygen makes up 276,900 ppm (parts per million) of the Earth's crust, or 46.6%. It exists as a major compound of the silicate minerals where it combines with other elements. read more
Aluminum is the third most common element in the Earth's crust. Aluminum is the crust's most abundant metal, but all the earth's aluminum has combined with other elements to form compounds, so it is never found free in nature. Aluminum oxide is a common aluminum compound. read more
The abundance of elements in Earth's crust is shown in tabulated form with the estimated crustal abundance for each chemical element shown as either percentage or parts per million (ppm) by mass (10,000 ppm = 1%). read more
Oxygen is the most abundant element in the Earth's crust. Oxygen makes up 276,900 ppm (parts per million) of the Earth's crust, or 46.6%. It exists as a major compound of the silicate minerals where it combines with other elements. It also exists as a compound in carbonates and phosphates. Oxygen has industrial, medical, and commercial purposes. read more
Together, these 8 elements make up more than 98% of the crust. The 8 most common elements in Earth’s crust (by mass): 46.6% Oxygen (O) 27.7% Silicon (Si) 8.1% Aluminum (Al) 5.0% Iron (Fe) 3.6% Calcium (Ca) 2.8% Sodium (Na) 2.6% Potassium (K) 2.1% Magnesium (Mg) The picture on the left shows where these elements are located within the periodic table. Together, the elements oxygen and silicon make up most of the Earth’s crust including silicate minerals such as quartz and feldspar. read more
