I heard that if we had the technology to have a higher proton count in an atom you would get a lighter and stronger alloy, any truth to this? What are some methods that are currently being used by scientists around the world? What are some newer alloys that are being developed that are much stronger then commonly found materials? Writing a short story for a class and was hoping to make it some what of a probable scenerio for technology in the near future. Thanks for any help you can offer.

No. Any atoms with a higher proton count are radioactive, and have a very short shelflife.But, I heard about the so called "island of stability" which might prove to be stable.A very strong material, although not an alloy, is carbon nanotubes.Another very strong alloy would be diamond engrained stainless steel.
