Describe one way in which the structures of diamond and silicon dioxide are similar.
Explain why the melting point of silicon dioxide is high.
When silicon dioxide reacts with hot concentrated sodium hydroxide, sodium silicate, $\text{Na}_2\text{SiO}_3$, is formed. Deduce the formula of the silicate ion.
Explain why diamond is unable to conduct electricity.
What does the term electrolysis mean?
Construct the equation for the reaction at the anode (positive electrode) in the electrolysis of molten aluminium oxide dissolved in cryolite.
Construct the equation for the reaction at the cathode, the negative electrode.
An isotope of silicon is shown as $^{29}_{14}\text{Si}$. Deduce the numbers of protons and neutrons in this isotope.
Define what is meant by relative atomic mass.
