Explain the reactivity of group $14$ elements towards oxygen.

(N/A) All members of group $14$ form oxides when heated in oxygen. They mainly form two types of oxides: monoxides $(MO)$ and dioxides $(MO_{2})$.
$SiO$ exists only at high temperatures.
Generally,oxides in higher oxidation states are more acidic than those in lower oxidation states.
Acidic oxides: $CO_{2}, SiO_{2}, GeO_{2}$.
Amphoteric oxides: $SnO_{2}, PbO_{2}$.
Among monoxides,$CO$ is neutral,$GeO$ is acidic,while $SnO$ and $PbO$ are amphoteric.
