(1992) Determination of the absolute isotopic composition and atomic weight of a reference sample of natural iron. Int. J. Mass Spectrom. 121, 111-125.Taylor, P.D.P., Maeck, R., De Bievre, P., 1992. Determination of the absolute isotopic composition and atomic weight of a reference ...
For the Mond nickel, in which a little iron was practically the only impurity, the same process was adopted, except that to remove alkalis the hydroxide was converted into sulphate and the latter subjected to electrolysis several times. After conversion into bromide, these were analysed, and for...
For example, the atomic weight of iron is 55.85 g/mol. Bohr atomic model electrons are assumed to revolve position of any particular electron electrons are assumed to revolve around the atomic nucleus in discrete(离散) orbitals, and the

He listened to the soft sigh of the swirling, iridescent iron atoms. MacLaurin was looking at him interestedly. "A queer body. His toes are long." "Uses them for fingers. I envy him. He can untie knots with them or run four-dimensional controls all at the same time." From THE SPACE...

In 1897 Charles Édouard Guillaume discovered that FeNi alloys with 36 wt% Ni have an exceptionally low CTE below the Curie temperature6. Around the Curie temperature, the CTE of the alloys increases drastically by up to one order of magnitude. This correlation of thermal expansion with the al...
