How many types of atoms have scientists found?
Counting only isotopes, and not ionic forms, there are over 1000 different nuclei for the 118 known elements. Most of these are unstable. Excluding bismuth, which is virtually stable, there are 80 stable elements and 254 stable nuclides out of 339 nuclides occurring naturally on Earth. Many more unstable nuclei have been created artificially, including all elements heavier than plutonium (94 protons). There are 80 elements with at least one isotope believed to be stable (assuming protons themselves are stable, which is uncertain; if they do decay, they do it VERY slowly). All isotopes of elements with Z>82 (more than the 82 protons in lead) are unstable, though bismuth-209 (Z = 83) might as well be stable: its half-life is considerably longer than the present age of the universe. The reason there are only 80 stable elements instead of 82 is that two lighter elements, technicium (Z=43) and promethium (Z=61), have no stable isotopes either.
What is hardest steel?
By Izod or Charpy impact strength, a widely-published property proportional to [fracture] toughness (which is barely to be found), the toughest metal is some grades of stainless steel (INCOLOY 803 [Fe:Ni:Cr:Al:Ti:C] claims 407 J; Gall-Tough PLUS [Fe:Cr:Ni:Mn:Si:Mo:N] claims 404 J.), then nickel alloy (Haynes Hastelloy B-3 [Ni:Mo:Cr:Fe], 358 J), then titanium (grade 1, 310 J; other grades are 100-200 J), then low-carbon steels (14-339 J).
