Hi,

Can someone please help me fix this MO diagram for SH.

I am not sure how to construct the MO for third row atoms in the periodic table such as sulfur. 
Please imagine the grey solid lines are dash lines and (*) represents antibonding.


Here is my work:

Thank you

Right so you only need to show the valence orbitals not the complete ones. Why would you show the complete orbitals when they are not involved in bonding....do they form a molecular orbital or do they stay as an atomic orbital?

Have a look at this molecular orbital diagram, especially the position of the atomic orbitals. http://www.google.co.uk/imgres?q=SH+molecular+orbital&um=1&hl=en&safe=off&sa=N&biw=1366&bih=643&tbm=isch&tbnid=bVAP4tKGXd7s6M:&imgrefurl=http://cnx.org/content/m34660/latest/&docid=FXAm2OmQ5l49ZM&imgurl=http://cnx.org/content/m34660/latest/graphics3.jpg&w=352&h=243&ei=7gZUT72qLIXJ0QXi5p3GCw&zoom=1&iact=hc&vpx=560&vpy=99&dur=10360&hovh=186&hovw=270&tx=102&ty=158&sig=114536966592323605498&page=2&tbnh=135&tbnw=203&start=21&ndsp=28&ved=1t:429,r:16,s:21

This should help you.
