Mg is 2.0% of Alkaline earth metals, as Ca is 3.6%..., equals 5.6%

it is extrackted from the earth by big drills
With a very sizable iron core and a (by comparison) wafer-thin crust, I doubt that the earth's crust even approximates a full percentage point.
The earths crust is a part of the outermost layer.
Silicon is a mixture of the minerals of the earths crust. so.... silicon isn't something from the earths crust. -thanks for your question.

No, other elemental categories, such as alkali metals and transition metals are also found on the Earth's crust. One such alkali metal that is frequently found on the Earth's crust is potassium (K).

Yes all metals are in the earths crust in ore form.

The name "Alkali" is given due to the alkaline nature of their oxides and hydroxides. The term "Alkali Earth Metals" is used as these metals are usually found as minerals in the Earth's crust.
About 7% of the earths crust
The percentage of Earth's crust is less than one percentage in terms of Earth's volume. The Earth's crust is actually a thin layer.
its the percentage in mass !
