Is the penny turning green like the statue of liberty turning green?
No, the green color on a penny comes from oxidation of the copper in the coin, while the Statue of Liberty turned green due to the natural weathering of the copper material it is made of over time. Different mechanisms are at play in these two situations.

What chemical property turns copper green if its left outside for a long time?
The substance would be... the copper itself! But it's not that trivial. The green substance is the product of the corrosion of copper and its alloys. In clean atmosphere product is called copper (II) dihydroxycarbonate [Cu(OH)]2CO3. The presence of sulphur dioxide in the atmosphere causes copper (II) dihydroxysulphate [Cu(OH)]2SO4 to be present in the corroded layer.
