The element has the lowest mass per nuclear particle is Iron, while hydrogen is the element with the highest mass per nuclear particle.
Cause "nuclear particle" here means particles forming nucleus, like proton or neutron. Hydrogen has just one proton, and an atomic mass of 1.00794, it's mass per nuclear particle is also 1.00794. For heavier elements like Iron, they have higher Atomic Mass but also more particles in their nucleus. For instance, iron has 26 protons and 30 neutrons, and an atomic mass of 55.847, it's mass per nuclear particle should be 55.847/(26+30)<1, which is much smaller than that of hydrogen.

What happens to the mass per nucleon in uranium when it is split into smaller nuclei?
The mass of the nucleon is decreased; the difference is released as energy.
What does the graph of mass per nucleon vs atomic mass number look like?
The graph of binding energy per nucleon versus mass number is an analog of this graph, except it would be upside down. Iron, which has the highest binding energy per nucleon, would have the least mass per nucleon as you looked across the periodic table. Use the link below to see the graph of binding energy per nucleon plotted against mass number. If you "invert" this graph, you'll have yours. If any uncertainty exists as to what is going on with "variable" mass among the nucleons of different elements, use the link below to the related question and investigate why things are the way they are.
Which element hasthe highest binding energy per nucleon Hydrogen Lithium Helium or Beryllium atomic?
Beryllium is it!
Can a hydrogen nuclear fission reaction restart the hydrogen fusion reaction?
No, hydrogen does not fission. Fission only occurs in heavy elements that are well past the peak in binding energy per nucleon (where binding energy per nucleon is decreasing), and fusion can only occur in light elements which are in the portion of the binding energy curve where binding energy per nucleon is increasing. When you fission a heavy element or fuse light elements, the product nuclei have higher binding energies per nucleon than the original element. This is where the energy release comes from. Check out the Wikipedia article on nuclear binding energy.
How does the mass per nucleon in uranium compare with the mass per nucleon in the fission fragments of uranium?
The uranium nucleus has over 200 MeV more mass than the sum of the masses of the fission product nuclei plus the free neutrons emitted. Most of this energy appears as the kinetic energy of those particles and manifests as heat energy. Enough heat energy to cause the air around a bomb to radiate x-rays.

What element has the greatest nuclear binding energy per nuclear particle?
We know that nickel-62 has the highest nuclear binding energy per nucleon of any element.
the mass defect for the nucleus of helium is 0.0303 amu what is the binding energy per nucleon for helium in MeV?
For helium the binding energy per nucleon is 28.3/4 = 7.1 MeV. The helium nucleus has a high binding energy per nucleon and is more stable than some of the other nuclei close to it in the periodic table.

What is the total number of nucleons on the planet Earth?
I would like to suggest the number 3.6007006 x 1051This is the mass of Earth divided by the mass per nucleon of Nickel-62. I have chosen Ni-62, because it has the highest binding energy per nucleon, and therefore the element at rest with respect to the Earth's potential.Comments: That's not a bad answer, but there are surely too many significant figures for an approximate answer. I'm not convinced by the argument for using nickel-62. Also, electrons do weigh something.
What is the order of binding energy per nucleon nucleus?
It is the division of the nuclear binding energy over the mass number.
How does the mass per nucleon in uranium compare with the mass per nucleon in the fission fragments or uranium?
This is not something I really know anything about, but I do know that energy is liberated in the process, so you could expect it to be less in the fission fragments. It also depends on the nucleus. Proton and neutron masses differ somewhat, so it depends on what the ratio of protons and neutrons is as well.
Why does not an atom of an element represent the actual mass of its atom?
The atomic mass of an element is measured not in the mass of the atom, but in the number of grams per mole.
