Step-by-step explanation:
The missing product of the reaction is BaCl2 and we can see that barium has two electrons on its outermost shell.
The complete reaction is Ba(ClO3)2 → BaCl2 + 3O2. From the reaction equation, we can see that the missing product is BaCl2. The compound is composed of one barium atom and two chlorine atoms.
Since chlorine has seven valence electrons, it means that it requires two electrons from barium to complete its octet in BaCl2. This now means that barium has two electrons in its outermost shell.
