How do most silicate materials form
Silicon and oxygen combine to form the most abundant mineral group, the silicates.
Most silicate minerals are formed when molten rock cools at either the earths surface, or deep underground.
Silicates contain mostly silicon and oxygen. The different types of silicate also contain other materials, but the base materials are silicate and oxygen
Feldspars are the most common silicate minerals.
Quartz is the most abundant single mineral. Feldspars are, as a group, the most abundant minerals. Quartz and feldspars are classified as silicate minerals, the classification of mineral with the most abundance in the Earth's crust.

Yes; that is implied by the name "silicate".

Positive

The simple answer is... Feldspar has a much higher complex and stable tetrahedral orientation in comparison to that of any other Silicate variation higher up on the reation series latter. Feldspar is one of the most stable variations in orientation of, what boils down to, silicate tetrahedra. Because Feldspar is technically a form of silicate tetrahedra orientation, I am assuming you are asking how the silicate tetrahedra orientations vary from its most simple (i.e. Olivine) to its mosts complex (i.e. quartz/FELDSPAR) forms. Esentially a Silicate Ion SiO4^-4 is the most basic building block of FELDSPAR. Knowing this, as you move from the top of Bowen's reaction series, we see a gradual stabilization of the various Silicate tetrahedral orientations. These orientations include (in order of stability/complexity): [TOP OF REACTION SERIES] Individual (Singular form) Silicate Tetrahedra (i.e. Olivine) Chain (Linear form) Silicate Tetrahedra (i.e. Pyroxine) Double Chain (Bilinear form) Silicate Tetrahedra (i.e. amphibole) Sheet Silicate Tetrahedra ('2-D' form) (i.e. Mica: Biotite or Muscovite) Framework Silicate Tetrahedra ('3-D' form) (i.e. FELDSPAR) [BOTTOM OF REACTION SERIES]

why do silicate materials have low electron density
Terrestrial planets have proportionately more silicate materials than Jovian ones.
Minerals form into crystals or clusters of crystals. In the crust, the most common individual mineral is quartz, and the most common class of minerals are the silicate minerals.
Basically, silicate is (SiO2)n.SiO32- so the other element is Oxygen (remark: compare silicate with carbonate CO32- )
