Why is it that when atoms get closer together the space between the nuclei are held apart? ! i have a packet to turn in tomorrow and i don't know the answer.

Two atoms far apart being brought closer to each other, their potential energy decreases until the nuclei repel each other (the repulsion). The nucleus of one atom is attracted to the electrons of the other atom. As the distance gets less, the potential energy gets less.

is has three carbons, so the answer is propylamine.
