Find the number of sesquioxide(s) from the following:

Solution

A sesquioxide is an oxide containing three atoms of oxygen with two atoms (or radicals) of another element. For example, aluminium oxide ( $A l_{2} O_{3}$ ) is a sesquioxide.

The number of sesquioxide(s) is 3.

$A l_{2} O_{3}, P b_{2} O_{3}, B_{2} O_{3}$ are the sesquioxides.
