I'm thinking that element 115,after completing assembly, can be formed in a cone shape, (point at top),for propulsion and shields the outer craft with the cooling property affect.

NASA funded the SLS and Starliner, I'm sure they will support this; ask them . . .

Go look up element 115 on wikipedia. It took undoubtedly many days of operation of a $100 million accelerator to produce a handful of atoms. How are you going to produce 10^28 or so atoms?? And how are you going to do it when the half life of the atoms is less than a second. You gonna make 10^28 atoms, form it into a spacecraft and fly the mission in a few seconds before it disintegrates?? And the decay heat of a macroscopic amount would vaporize your spacecraft and crew in a fraction of a second (think trillions of trillions of 60 megaton Tsar Bomba detonations within a few seconds of each other. Think all this through and get back to us . . . .

Not sure how a hunk of metal would provide propulsion, even for the few seconds it would exist.
Not surprising, it does not. He's got some fuzzy idea that radioactive = nuclear energy = can use for rockets. Likely half remembers something about antimatter rockets, which is actually less ridiculous than Element 115 rockets . . . . We should lobby NASA to ship the idea to Roscosmos . . . . :)

According to contemporary nuclear physics, Element 115 is next door to Element 114 which is at an island of nuclear stability. However this island of stability is around 184 neutrons with a closed neutron shell in the nucleus for Element 114 or nearby ones like Element 115, 113 etc. It is predicted that nuclei at or much closer to the so-call magic number of atomic nuclei with 184 neutrons could have half-lives or thousands of years or more but so far only isotopes with the high 170s of neutrons have been produced for Element 115 or 114, 113, 116 etc. And yes this would still be expensive to produce atomic nuclei in this way.

There might be more of these heavier super-heavy nuclei closer to those having 184 neutrons produced soon when the Facility for Rare Isotope Beams comes on-line at Michigan State University, likely some time in 2022.

How are you going to build about 1,000,000,000,000,000,000,000,000,000 or more particle accelerators at a hundred million dollars each, collect their output atoms, build a spacecraft, launch it and have it carry out it's mission in a few seconds before all the atoms decay. Not considering that the mass of atoms would explode with about the force of 1,000,000,000,000 of the largest nuclear weapon ever exploded, with a fireball 6 miles in diameter?? How?? None of these superheavy nuclei have long half lives more than a few seconds, one on an island of stability may have a half life of a minute AT MOST. You going to construct, launch and have it fly a mission in a couple minutes while it disintegrates in an earth-sized fireball?? I have a PhD nuclear physics, I've actually studied the shell model. No nuclei out in any island of stability will have a half life of more than a handful of seconds. And you would still need not 1, not 10, not 1000, not 1,000,000 accelerators to make the material, you would need the number quoted at the top. How you gonna build all those?? These atoms are made a handful at a time. The posting guidelines prevents me from commenting more pungently on your ideas and comments. Address the above.

Even with that aside, still not sure the advantage of this element. The nose cone is used to allow the spacecraft to navigate through the atmosphere until it gets into space, then it’s usually discarded. The cheapest material that works would be the best.
