Oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium are the most common elements found in Earth's continental crust.
Hydrogen is the most common element in the universe. Helium, Oxygen, silicon, and aluminum are the next most common elements in the universe and on earth.
Helium is not one of the 8 most common elements in Earth's continental crust. The 8 most common elements are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. Helium is a noble gas and is not as abundant in Earth's crust compared to these elements.
The two most common elements in Earth's crust are oxygen and silicon. Oxygen makes up about 46.6% of the Earth's crust by weight, while silicon makes up about 27.7%.
