In this problem, you will compare Lewis$/$VSEPR theory and Covalent Bond theory to experimental data. The experimental photoelectron data for $Ne,HF,H_{2}O,N{H}_3,$ and $C{H}_4$ are shown below. Photoelectron spectroscopy measures the filled Orbitals of a molecule. For each molecule, draw the structure using Lewis formalisms and give the geometry using VSEPR structure. Answer questions regarding Lewis$/$VSEPR prediction using this structure combined with your assigned point group for the structure.

Neon

a$)$ Draw the Lewis$/$VSEPR structure for $Ne.$

b$)$ How many separate electron energy levels does the Lewis$/$VSEPR structure predict?

c$)$ Write down the electron configuration for Neon.

d$)$ For each major feature observed in the spectrum, give the energy of the transition and assign the orbital$($s$)$ from which the electron comes.
