This is a table that shows the elemental chemical composition of the Earth's crust. Keep in mind, these numbers are estimates. They will vary depending on the way they were calculated and the source. 98.4% of the Earth's crust consists of oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. All other elements account for approximately 1.6% of the volume of the Earth's crust.
