It depends on how you look at it. The actinides series look like the last because they are always extended out of the bottom, so if we are going by the last in the actinides, then it would be No (Nobelium). However, if you are looking at the one with the highest atomic weight it would be Ununoctium with an Atomic Mass of 293 mol.g-1. It is number 118 on the Periodic Table, and does not exist in nature.
