Reactivity of silicon

[PromProm]

What would the the approximate position of silicon on the reactivity series?

 

p.p.

generally it's only metals that are on the (re)activity series. Having said that, the reactivity series is often described as being the exact opposite order of the increasing electrode potentials (electrochemical series). The difference is that in the electrochemical series, elements are listed as being oxidised/reduced even if the resulting compound(s) is(are) not ionic. The two interesting lines on the electrochemical series as far as you're concerned are:

 

the reduction of silicon to silane (SiH4) and

 

the oxidation of silicon to silica (SiO2)
