The crust which is about 7 miles thick contains the all of the element metals we have discovered so far because no one has ever drilled all the way through the crust.
The Earth has layers because it is made up of materials of varying density.

Crust and mantle
The various layers inside the earth range from solid rock, like the crust, to liquid metals, like the earth's outer core.

Inner core and outer core.
Because of gravity, the Earth's inner layers consist of the heavy elements, mainly metals. The heavy and radioactive ones are the origin of most of the heat.

Earth's compositional layers are the crust, mantle, and core, based on the materials they are made of (silicates vs. metals). Structural layers are based on their physical properties and include the lithosphere, asthenosphere, mesosphere, outer core, and inner core. The main difference is that compositional layers are defined by chemical differences, while structural layers are based on physical properties like temperature and behavior.
Yes it is
The Earth's core is mostly made of nickel and iron. It is divided into the outer core, which is liquid, and the inner core, which is solid. These two layers primarily consist of these heavy metals.
