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)
Silicon makes up 27.7% of the earth's crust.

silicon percent abundance in earths crust poops
Nitrogen
That would be Nitrogen.

Calcium it's calcium here's proof if u don't trust me http://www.webelements.com/calcium/
silicon percent abundance in earths crust poops
Silicates make up close to 95 percent of the rocks in the Earth's crust
Nitrogen
the element of find onther place to look it up
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.
That would be Nitrogen.
The principle element found at the Earth's core is iron.
Nitrogen, which is an element. It has atomic number 7 on the Periodic Table of Elements.
