Also, as I write down key points and assemble an outline and structure, I can draw quick ideas for visuals such as charts or photos that will later appear in the PowerPoint. The structure and binding of electronic excited states is, in almost every case, weaker than the ground electronic state, and the interatomic forces and vibrational frequencies. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. From an analysis of the electronic band structure close to the Fermi level, we have quantified the gradual change in the Fermi surface topology from the point-like structure for graphene to a warped triangular shape for graphite.
