Question
Only need help on number one with chart. I only need the hydbridization part.
I UI valenčé electrons for an atom
draw valence orbital energy diagrams (recall how each orbital is shaped)
draw Lewis structures, identify electron groups, and use VSEPR to predict bond angles
1. The first key to success with VB theory will be to understand the connection between bond angles and une
number of electron groups. Complete the first three columns (leave the last column blank for now) 0n the
table below without looking up the chart in your book.

2. Next you will need to be able to draw valence orbital electron energy level diagrams to identify what orbitals
can overlap to form bonds. Using the provided example as a guide, write valence orbital diagrams for the
below atoms. Then determine the number of bonds that could form by counting the singly occupied orbitals.
Does this match what is expected for some known molecules with these atoms?

3. Remember that VB theory describes bonds as orbitals overlapping. What orbitals would overlap in H-Cl?
