The nature of bonding in metals, insulators, and semiconductor elements has to be explained. Concept introduction: Nature of bonding in a compound has to be described by the most familiar method molecular orbital theory. The bond formation between atoms has to be clearly known by using this method. Molecular orbital theory: The interaction between two atomic orbitals gives new bonding and anti-bonding orbitals. These molecular orbital have energy gap, depending on energy gap these orbitals are closely spaced which is said to be band. The closely spaced filled energy levels will make the valence band. The upper half of the energy levels belongs to the empty, delocalized molecular orbitals. This set of closely spaced empty levels is said to be conduction band. Depending on these valence band and the conduction band the mobility of electrons in an atoms can easily we can say.

Technetium is the first element in the periodic chart that does not have any stable isotopes. Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half life ideally suited for medical tests. It would seem that the decay of technetium should fit the treatment above with the result In(c/c) = -kt. The table below includes data from the two sites: http://dailymed.nlm.nih.gov/dailymed/druginfo.cfm?id=7130 http://wiki.medpedia.com/Clinical: Neutrospec_(Technetium_(99m Tc)_fanolesomab). a. b. C. Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also graph In(c/c.) on the vertical axis versus time on the horizontal axis. When half of the original amount of starting material has hours fraction remaining disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the material to decay away). Determine the slope of your In(c/c.) vs t graph and…
