Valence-shell configuration and periodic trends

Postby Rachel Caprini 1E » Mon Nov 14, 2016 6:53 pm

How can we explain periodic trends in terms of valence-shell configurations and MO diagrams?

Molecular orbitals can help explain periodic trends in electronegativity, ionization energy, and electron affinity in the same way as atomic orbitals and electron configuration. Incomplete molecular orbital = easier to pull off an electron while molecular orbital with two electrons is harder.

What does it mean to have overlapping atomic orbitals? What is meant by the greater splitting energy that results in more overlapping?
