The table lists the melting points for $\text{SiO}_2$ and $\text{P}_4\text{O}_6$. $\text{SiO}_2$: $1883\,\text{K}$ $\text{P}_4\text{O}_6$: $297\,\text{K}$ Which statement accounts for the difference in the melting points of $\text{SiO}_2$ and $\text{P}_4\text{O}_6$?
- AThe bonding of the oxides changes from ionic to covalent.
- BThe metallic character of the elements decreases across Period 3.
- CThe oxidation number of the element increases from Si to P.
- DThe structure changes from giant molecular to simple molecular.
