Cobalt

  Lewis structures are unable to render Cobalt very well.  Generally, Lewis structures are only used through the third period as the Aufbau principle and correct filling of electronic configurations breaks down around the element Chromium early in the fourth period.  Gooch structures B renders all 118 of the elements using consistent symbolism.

  Cobalt occupies the same place in its period as Carbon and Silicon do respectively in their periods.  All life found on the planet is Carbon based.  Silicon is the base element for the construction of electronic logic gates in computers.  Cobalt should be examined very closely for properties that are similar to Carbon and Silicon.

  Notice how there are an equal number of arrows facing in as face out in the Gooch structure B of Carbon (above).  These arrows represent bonding sites and the molecular orbital equivalent of "equally being able to give up or take on outer "shell" electrons".  The vector bonding definition is that it has an equal amount of keys and keyholes - the two different types of bonding sites.  The standard model has no equivalent of a keyhole bonding site and no Lewis structures contain them.  However, the use of these sites has led to linear aufbau configurations for all seven periods and molecules which need no hybridization or hybrid structures - one structure only for each molecule.
