Corrections? Titanium is a lustrous transition metal with a silver color, low density, and high strength. It is now known that uranium, radioactive in all its isotopes, consists naturally of a mixture of uranium-238 (99.27 percent, 4,510,000,000-year half-life), uranium-235 (0.72 percent, 713,000,000-year half-life), and uranium-234 (0.006 percent, 247,000-year half-life).

Iron is a metal in the first transition series. Electronegativity, symbol , is a chemical property that describes the tendency of an atom to attract electrons towards this atom. This affinity is known as the second electron affinity and these energies are positive. Compressibility (also known as the coefficient of compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change. Covalent bonds often result in the formation of small collections of better-connected atoms called molecules, which in solids and liquids are bound to other molecules by forces that are often much weaker than the covalent bonds that hold the molecules internally together.
