Answer:
Lewis structure is shown below.
Explanation:
For selenium dioxide molecule, [tex]SeO_2[/tex]
Valence electrons of selenium = 6
Valence electrons of oxygen = 6
The total number of the valence electrons = 6 + 2(6) = 18
The Lewis structure is drawn in such a way that the octet of each atom in the molecule is complete. So, the Lewis structure of the molecule is shown in the image below.
