The core is primarily made of molten iron, so that would be my guess. It is that swirling molten metal that is responsible for our magnetic field.

Aluminum is the most abundant metallic element in the earth's crust. If you could measure the whole earth, iron might win. And since each atom of iron weighs twice as much as an atom of aluminum, measure by weight and iron wins easily.

Aluminum is the most abundant metallic element on the surface of the Earth. This light metal comprises more than 8 percent of the Earth's crust. It is also the most abundant metallic element on the surface of the moon.
Aluminum does not exist in a pure form in nature. It is always found in mineral forms, in combination with oxygen, sand, iron, titanium, clay, or other substances. The principal ore of aluminum is a rock called bauxite (aluminum hydroxide). Nearly all rocks, particularly igneous rocks (rocks of volcanic origin), contain some aluminum in the form of aluminosilicate (aluminum plus silicon dioxide) minerals.

Hi. IN Earth? Iron. ON Earth? Aluminum.

Iron is the correct answer. Silicon is a semiconductor, not a metal.

Silicon, aluminum, iron, and oxygen are the most abundant in the earth.
The percents are:
(Approximate % in Earth)
Oxygen --- 46.6%
Silicon --- 27.7%
Aluminum --- 6.5%
Iron --- 5%
Calcium --- 3.6%
Sodium --- 2.8%
Potassium --- 2.6%
Magnesium --- 2.1%
ETC.
Since you want to know the most abundant metallic element in earth, then it would be ALUMINUM.

I would guess lead because it is among the lowest valued metals on the market.
