Halite is another name for common salt - chemical formula NaCl (Sodium Chloride)
Silicate is the mineral made of silicon and oxygen.
The main constituent of sand is Silicon Dioxide. This compound contains silicon and oxygen.

SiO4 (silicon-oxygen complex) is a complex that contains one silicon and four oxygen.
Quartz is made up of a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two Si-centered tetrahedra, giving an overall formula SiO2.So quartz has two Oxygen atoms to one Silicon atom.
"silicon-oxygen" is essentially meaningless. Silica contains silicon and oxygen in the proportion 1:2, so is sometimes called "silicon dioxide", but it doesn't exist in the form of individual SiO2 molecules; they're bonded to each other in a large network.
SiO2 is a macromolecule. Each silicon atom is covalently bonded to four oxygen atoms and each oxygen atom is covalently bonded to two silicon atoms.
Silicon (a metalloid) and oxygen (a nonmetal) are the two elements that compose silicon dioxide (SiO2).
Silica (or silicon dioxide) is a mineral that contains only oxygen and silicon. It is one of the most abundant minerals on Earth and is commonly found in the form of quartz.
