WebIn case of conductor, electrons fill the conduction band partially. The overlapping of both the bands i.e. valence and conduction band also take place. This shows that no forbidden energy gap is present. In case of semiconductors the conduction band is empty and the valence band is fully filled with electrons. drama\u0027s e4WebBand theory is a method that calculates the energy gap in electrons of a specific solid to separate two kinds of bands, namely Valence bands and Conduction bands.

All this assumes that you have studied the basics of band theory (if not the Wikipedia article is good.) The theory predicts that metals will conduct (both heat and) electricity very well and so is generally accepted. drama\u0027s dyBefore starting this session, you should be familiar with prior topics from Structure of the Atom (Session 1 through Session 7) and Bonding & Molecules (Session 8 through Session 12), specifically: 1.
