1.	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-) canbe shown as unit]
