There are two types of chemical bonds, covalent and ionic. Ionic bonds involve the complete transfer of electrons and covalent bonds share electrons. In quartz, or SiO2, the electrons are shared, so it is a covalent bond.
Since silicon is a metalloid and oxygen is a non-metal, the bond is considered to be an ionic bond.

A silicon-oxygen tetrahedron.
Silica is NOT made of nitrogen and oxygen. It is actually made of silicon dioxide which means it's made of silicon and oxygen.
It is classified as a silicate.

Quartz.
It is classified as a silicate.
Silica - commonly known as quartz is formed of silicon and oxygen having the chemical formula SiO2.
A silica tetrahedron is composed of a central silicon cation surrounded by four SP3 bonded oxygen anions. The angle formed between the oxygen - silicon - oxygen ions (O-Si-O) varies between 140 and 180 degrees depending on the specific type of silica. Please see the related links.

Silicon (and oxygen).
The chemical formula of silicon dioxide is SiO2. The atomic ratio oxygen/silicon is 2.
There are 4 oxygen ions and 1 silicon ion in a silicon- oxygen tetrahedron.
Most likely not. Silicate minerals contain silicon in combination with oxygen. However, silicon itself is considered a non-silicate mineral, composed entirely of the element silicon; without the oxygen, however, it IS a non-silicate mineral.
