Energy of valence electrons from period of the periodic table

Click For Summary
SUMMARY

The discussion focuses on the relationship between the energy of valence electrons and their position in the periodic table, specifically comparing silicon (Si) and germanium (Ge). It establishes that the energy band formed by overlapping atomic orbitals is influenced by the energy levels of the valence electrons, which vary across periods. The participant suggests that the energy trends of these valence electrons correlate with their ionization energies, indicating a systematic change as one moves down the periodic table.

PREREQUISITES
  • Understanding of atomic orbitals and their role in energy band formation
  • Familiarity with the periodic table and periodic trends
  • Knowledge of ionization energy and its significance in chemistry
  • Basic principles of electrical engineering related to semiconductor materials
NEXT STEPS
  • Research the energy band theory in semiconductors
  • Study the ionization energy trends across different periods of the periodic table
  • Explore the properties of silicon and germanium as semiconductor materials
  • Investigate the effects of atomic orbital overlap on electrical conductivity
USEFUL FOR

Electrical engineering students, chemists, and materials scientists interested in semiconductor physics and the behavior of valence electrons in relation to periodic trends.

TL;DR
This thread is about the energy of energy bands relative to the period of the periodic table(same group)
I am currently studying Electrical Engineering and I have this question: An energy band is formed by the overlapping of atomic orbitals of atoms coming close to each other.I suspect that if the energy of the atomic orbital of the valence electrons of a chemical element is less than the energy of the atomic orbital of the valence electrons of a different chemical orbital then the energy band formed by the overlapping of many orbitals of the first chemical element will be lower in energy than the energy band formed than the energy band formed of the second chemical element.How is the energy of the valence electrons affected by change in the period of the periodic table?(e.g energy of Si 4 valence electrons vs energy of Ge 4 valence electrons)?

I would think the energy trends would reflect the ionization energy of the valence electrons.
