Potassium is the answer. Below are 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 fifth most abundant element in the Earth's crust is potassium. It makes up about 2.6% of the Earth's crust by weight.
Oxygen is the most abundant element in the Earth's crust, making up about 46.6% of its mass.
The element found in both biotite mica and muscovite mica that makes up the greatest percentage by volume of Earth's crust is oxygen. Oxygen is a very abundant element in the Earth's crust, forming the majority of the minerals and rocks that make up the Earth's surface.
Nitrogen makes up 78% of Earth's atmosphere.
This element is calcium. It is the fifth most abundant element in the Earth's crust and makes up more than 3 percent of the crust. It reacts with water and belongs to the 2nd group of the periodic table.
Silicates make up close to 95 percent of the rocks in the Earth's crust

The element found in both biotite mica and muscovite mica that makes up the greatest percentage by volume of Earth's crust is oxygen. Oxygen is a very abundant element in the Earth's crust, forming the majority of the minerals and rocks that make up the Earth's surface.
In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
Nitrogen makes up 78% of Earth's atmosphere.
This element is calcium. It is the fifth most abundant element in the Earth's crust and makes up more than 3 percent of the crust. It reacts with water and belongs to the 2nd group of the periodic table.
The principle element found at the Earth's core is iron.
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.
Nitrogen, which is an element. It has atomic number 7 on the Periodic Table of Elements.
Iron makes up approximately 5% of the Earth's crust, followed by aluminum at around 8%. Therefore, neither of these elements make up 3%. Carbon is present in trace amounts in the Earth's crust, around 0.02%, while silicon is the most abundant element at about 28%.
