Why are the properties of CO2 and SiO2 different?

Their properties are very different because CO₂ is a chain-like three-atom  molecule and SiO₂ is a solid compound with the three dimensional bridges between silicon and oxygen atoms.

Why trimethylamine amine ( N(CH3)3) is tetrahedral while trisilyl amine (N(SiH3)3) planner.?

Nitrogen (N) atom in trimethylamine [N(CH3)3] is sp3 hybridised and tetrahedral due to non bonding electron pair of N is localised (more basic). On the other hand N atom of trisilylamine [N(SiH3)3] is sp2 hybridised and trigonal planner.This is due to the participatlon of non-bondlng pair of N into pπ-dπ back banding. Due to this delocalization of non-bonding electron pair of N in trisilylamine it is also less basic.
