Answer : The Lewis-dot structure of [tex]RbIO_2[/tex] is shown below.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is, [tex]RbIO_2[/tex]
As we know that rubidium has '1' valence electrons, iodine has '7' valence electrons and oxygen has '6' valence electrons.
Therefore, the total number of valence electrons in [tex]RbIO_2[/tex] = 1 + 7 + 2(6) = 20
As we know that [tex]RbIO_2[/tex] is an ionic compound because it is formed by the transfer of electron takes place from metal to non-metal element.
