In Kekule structures, the bonding electrons are drawn as lines and the lone-pair electrons are usually left out entirely, unless they are needed to draw attention to a specific chemical property

Yeah, Emerson is right. Its the hexagonal benzene ring, with the three double-bonds staggered. Dosen't matter where you draw the bonds as long as they alternate. The two possible ways of drawing that are virtually the same. They are resonance structures, because in reality the electrons they represent are resonating all over the ring. This is why you often see the benzene ring as a hexagon with a circle in it, representing the circulation of the electrons. Such structure is not limited to benzene, it is also found in pyridine and cyclopentadiene. Anything where the Hueckel number of electrons is present.
All such molecules are called aromatic or arenes.
Great chemist August Kekule famously solved the mystery of benzene's structure in the 19th century. He said he woke from a dream in which he imagined how the benzene carbons bond.

kekule structure is given to the hexagonal shape of the benzene ring.
