It si one of only a few materials that is a conductor but has the advantage of being extremely abundant and relatively cheap

Silicon reacts with fluorine
Silicon also shows catenation ...but only till 8 atoms.
Quartz is silicon dioxide (SiO2); quartz is not a property.
It strictly means the temperature coeffecient of a particular property of silicon: as the temperature rises, the value of this property falls. Such as electrical resistance.

Silicon is a brittle material and does not exhibit ductility or malleability. It is a semiconductor that is commonly used in electronic devices due to its unique electrical properties.
Sand is a natural product (frequently silicon dioxide or calcium carbonate) not a material property.
The blue-gray color of silicon is a physical property. Physical properties are characteristics that can be observed or measured without changing the composition of the substance, like color, density, and melting point.
Additions of silicon make *Aluminium and Tin/Copper (bronze) alloys stronger, stiffer, more resistant to wear.
A: Because the element has different property as gallium arsenide.
That silicon could possibly be the basis of an alternate bio-chemistry. In fact the 'organic' properties of Silicon are severly limited in comparison to Carbon and require very special and limited conditions to be valid in.
