Part C 1. Sketch the structure of a Pa molecule. Each atom is bound to the other three by single bonds. Use the flexible links to make a model 2. Sketch the structure of an Se molecule. Each atom is bound to two others forming a ring. Use the black spheres and short gray connectors. It should be possible to angle the bonds so that four atoms (every other atom in the ring) can rest on the table top while...
