Title: What is the chemistry of silicon?
Post by: scientizscht on 09/11/2018 21:45:54
hello!

Can anyone outline chemistry of Silicon?

the major properties and behaviour?

thanks!

Wikipedia isn't a bad place to start: https://en.wikipedia.org/wiki/Silicon#Characteristics

Books have been written about the chemistry of silicon.


What bits did you have in mind?

Reactivity mainly

At or near room temperature, silicon doesn't react much with anything except fluorine  and (I think) chlorine trifluoride. You might get more reactivity with very finely powdered material.

Why do you ask?
Also, is there a re reason you couldn't find out about its reactivity from, for example, this?

Out of interest, how is silicone made?

Differently from silicon.

Incorrect. As Bored Chemist already pointed out silicon and silicone are not the same thing.

Elemental silicon reacts with oxygen (at high temp, or with high surface area), fluorine, concentrated solutions of KOH or NaOH, and when finely divided, mixed with active metals such as lithium or magnesium and heated, it will form metal silicides (other metal silicides can also be formed, with more forcing conditions, or more roundabout methods).
