Question

Determine the number of bonding electrons and the number of nonbonding electrons in the structure of SI2.
Enter the number of bonding electrons followed by the number of nonbonding electrons, separated by a comma, in the dot structure of this molecule (e.g., 1,2). 

 

IS it 2,16. Thanks and have a nice day!

Answer 1

You have 2, 16 which adds up to 18 total electrons.  If your compound is SI₂, meaning sulfur di-iodide, then you need to have 20 electrons.  The Lewis dot would show 4 bonding and 16 nonbonding electrons.  Or 4,16.  If you actually meant to ask about SiI₂ (silicon di-iodide) then you would be correct.
