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.
As oxides, silicates, aluminates, and/or sulfides.
silicates
silicates are minerals so perhaps you mean what elements are in silicates? , OR are you asking what are some silicate minerals?
The core is considered the center of Earth because it is at Earth's geometric center.
In the center of the Earth. Where did you THINK it was?
