i think its potassium
The most abundant metal in the earth crust is aluminium.
half of earths layer
Aluminum is an abundant element in Earth's crust and is not "bad" for the Earth, although it may be "bad" for organisms in the biosphere in certain concentrations.
Silicon is the element in the Earth's crust that has 14 protons. Quartz is crystallized Silicon Dioxide. Flint is also silicon dioxide. The compounds of Silicon are known as silicates.
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
That element is Oxygen by 46.6%
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
Oxygen is the most common and abundant element in the Earth's crust having 47% of the mass.
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.

Aluminum 7.5 to 8.1%
Siliconsilicon at 28%silicon!
That would be silicon, or SiO2
