Example of nuclear fission and nuclear fusion​

In fission, energy is gained by splitting apart heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium.

a. is the answer because they are not shared

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
