Question

for SeO2
explain bonding in molecule. indicate the type of bond and the underlying atomic orbitals that go into each. include the location of an unshared electrons

Answer 1

• The Lewis structure for SeO₂ has 18 valence electrons available to work with.
• SeO₂ is a Lewis structure with Selenium (Se) which can hold more than 8 valence electrons.
• It's a good idea to check the formal charges for your SeO₂ Lewis structure to make sure they are zero. The first structure you come up won't have formal charges equal to zero and therefore is not the best structure for SeO₂.

molecular structure and bond angles

1- Count number of valence electrons
2- Connect outer atoms to central atom by a single bond.
3- Assign electrons to outer atoms to central atom to insure that each outer atom has an octet.
4- Assign remaining electrons to central atom (in this case there are 2 electrons remaining after 16 electrons are assigned to the 2 oxygen atoms).
5- Create double bonds as required to fill the octet on the central atom (in this case 1 double bond is required to do that).
