Silicon is the second most abundant element `(~27.2%)` in the earth's after oxygen `(45.5 %)` Carbon. Silicon, germanium, tin and lead constitute the group `14` of the periodic table. Chemistry of silicon is distinctly different from that of carbon.
For example, under standard conditions `CO_(2)` is a gas whereas `SiO_(2)` is a covalent solid.
Draw the structure of a cyclic silicate having structural formula of `[Si_(6)O_(18)]^(n-)`.Also determine the value of `n`
[Hint : `SiO_(4)^(4-)` can be shown as unit]
