to be of any use. E-213 is used in spacecraft shielding and 187 and 152 are
used as HEAVY metamaterials which can easily MIMIC the properties of a variety of
I should note that isotopes of E116 and E115 are part of the
island of stability in that atomic number range which will be
found and publicly disclosed soon enough.edit on 2013/8/28 by StargateSG7 because: Oh Yeah!

TBF, the island of stability is common knowledge, and with the Government's honesty level at an all time low, it wouldn't shock me to find that secret research (especially in this field) is far ahead of what we are allowed to know.
All the reported above isotopes of element 115, obtained by nuclear collisions of lighter nuclei, are severely neutron-deficient, because the proportion of neutrons to protons needed for maximum stability increases with atomic number. The most stable isotope will probably be 299Uup, with 184 neutrons, a known "magic" closed-shell number conferring exceptional stability, making it (with one further proton outside the "magic number" of 114 protons) both the chemical and the nuclear homolog of 209Bi; but the technology required to add the required neutrons presently does not exist. This is because no known combination of target and projectile can result in the required neutrons. It has been suggested[by whom?] that such a neutron-rich isotope could be formed by quasifission (fusion followed by fission) of a massive nucleus, multi-nucleon transfer reactions in collisions of actinide nuclei, or by the alpha decay of a massive nucleus (although this would depend on the stability of the parent nuclei towards spontaneous fission).

I was honestly thinking you were talking to aliens, sorry your sarcasm was lost on my feeble mind.
Admittedly I also know little about nuclear physics, so what your telling me is that there is a island of stability associated with heavy elements and when we start learning to explore this island properly we will find stable yet heavy isotopes?
So what uses could we have for elements like 115 or past 118?
Also just how far can you see the periodic table going in terms of super heavy elements whether made naturally or in a lab?
Expended periodic table
I have been reading this, fascinating stuff but isn't a lot of it just hypothetical?

Mercury is an interesting metal, and the current science has not been able to utilize it.
Bob Lazar's account seems fictitious to me.
The experiment consisted of firing ions of a rare isotope of calcium (48Ca) at targets made of thin films of americum (243Am) created at Oak Ridge National Lab in the USA. Occasionally (1.5 times per day on average), these two elements fused to form an isotope of element 115, with a mass number of 288. Although the element has a half life of 140-190 milliseconds, it's presence was proven by the characteristic chain of more stable decay products it leaves behind.
