Take home points on atoms and molecules.
Scanning tunneling microscope allowed seeing atoms well. [1986 Nobel Prize: Binnig and Rohrer]
Fe = iron atom on silver surface (Ag);|
CO - for carbon-monoxide on Ag.
(A) Tip induces detachment of CO and bonding to tip;
(B) tip with CO move toward Fd atom on surface
(C) tip reverses process, detaching CO to surface; (D) single Fe-CO bond formed.
|(A) Five Fe atoms and five CO molecules on Ag surface.
(B) formation of Fe-CO shown in whole figure above.
(C) Another Fe-CO formed.
(D) Second CO moved to Fe-CO to form Fe(CO)2.
