Silicate - derived from silica which is a component of glass.

Like all crystals that are formed through oxidation or for some reason a high-pressure gas, quartz is also the same.

Therefore dioxide comes next to its chemical composition.

SiO2 makes nonpolar bonds, it's so easy to move in all directions.

Chemically, quartz is a compound called silicon dioxide.

When a crystal of quartz is properly cut and mounted, it can be made to vibrate, or oscillate, using an alternating electric current; each oscillation, in turn, causes a voltage change across the crystal, which can be detected by a suitable electronic circuit. The frequency at which the crystal oscillates is dependent on its shape and size, and the positions at which electrodes are placed on it.

If the crystal is accurately shaped and positioned, it will oscillate at the desired frequency; in clocks and watches, the frequency is usually 32,768 Hz, as a crystal for this frequency is conveniently small, and as this frequency is a power of two and can easily be counted using a 15-bit binary digital counter.

In sio2 only the quartz metal is found.

Quartz is obtained from the pure form of silicon dioxide (sand).

Which liquid is metal?

Is correct.

Quartz is crystal, but it is not a chemical product.

Quartz is a crystal and also silicon dioxide (sand).

A hard glossy mineral consisting of silicon dioxide in crystal form; present in most rocks (especially sandstone and granite); yellow sand is quartz with iron oxide impurities.
