No that is not true. Earth formed from the solar nebular and as it formed it would be, throughout, a mixture of the stuff in the nebula (including silicates). After it reached a certain size, it then melted entirely and the materials it was made form separated out one form another on the basis of their density. At this point the heaviest stuff (the metals) fell to the core and the lightest stuff (the silicates) floated to the surface. BUT in the beginning of Earth's formation there was no such differentiation.
What else can I help you with?
Where are minerals and metals on earth found?
As oxides, silicates, aluminates, and/or sulfides.
What are two big groups of minerals called?
Silicates and non-silicates are the two big groups of minerals. Silicates are the most abundant mineral group on Earth and contain silicon and oxygen, while non-silicates include minerals such as carbonates, sulfides, oxides, and native elements.
Make up close to 95 percent of the rocks in the Earth's crust.?
silicates
Is the heaviest material is at the outside of the earth?
No, the heaviest materials are not located at the Earth's surface. Instead, denser materials, such as iron and nickel, are found in the Earth's core, while lighter materials, like silicates, are found in the crust. This differentiation in density is due to the process of gravitational differentiation that occurred during the formation of the Earth. Thus, the heaviest elements are concentrated toward the center, not the outside.
Why are silicates so common in Earth's crust?
Next to oxygen, silicon in the form of silicate minerals is the most abundant element in the rocks of the crust. As these rocks are weathered and eroded, the silicon becomes part of sedimentary rock.

What are the largest group of rock forming minerals?
Silicates are the largest group of rock-forming minerals. They are characterized by silicon and oxygen atoms combined with other elements such as aluminum, iron, calcium, magnesium, and potassium. Silicates make up about 90% of the Earth's crust.

Most common groups of minerals on earth?
The most common groups of minerals on Earth include silicates, carbonates, oxides, sulfides, and sulfates. Silicates are the most abundant group, making up about 90% of the Earth's crust. Carbonates are commonly found in sedimentary rocks, while oxides, sulfides, and sulfates are often formed through chemical processes involving oxygen and sulfur.
