  Transition metal Summary
Transition elements, or metals, are a category of materials in the periodic table that are set apart from the "major group" or "A series" elements by their ability to use either the penultimate and outermost electron shells to bond with other substances.
The (loosely defined) transition metals are the 40 chemical elements 21 to 30, 39 to 48, 71 to 80, and 103 to 112.
Transition elements tend to have high tensile strength, density and melting and boiling points.

However, many interesting properties of the Transition elements as a group are the result of their ability to contribute valence electrons from s orbitals before d orbitals, a property which all members of the d-block except zinc and scandium share, so the More restricted definition is in many contexts the More useful.
The (loosely defined) Transition metals are the forty chemical elements 21 to 30, 39 to 48, 71 to 80, and 103 to 112.

 Charles Bury on Electronic Structure in 1921
As in the previous transition series in the first long period, the lower valences of the first transition elements lead to the formation of unstable compounds; ruthenium and rhodium divalent salts are unstable.
The last transition element, palladium, shows the same preference for the lower valences that is characteristic of cobalt and nickel; palladium trioxide and its derivatives are unknown, and palladium alone, of this series, forms stable divalent salts.
The second 8-18 transition series was shorter and more sudden than the first, possibly because of the greater stability of the groups of 8 and 18 electrons in the fourth, than in the third shells; and the elements of the second transition series showed but little resemblance to those of the first.

 Press fitting element - Patent 6474699
The press fitting element of claim 1 wherein the cord diameter of the sealing ring is smaller, when the main body is made of copper, than the cord diameter of the sealing ring, when the main body is made of carbon steel or high alloy steel.
The inner diameter of the non-deformed sealing ring, which forms a torus, is at least equal to or greater than the inner diameter of the cylindrical portion.
As a consequence of the steeper profile of the transition 6, the so-called B-value of the press fitting element according to the present invention and labeled by reference numeral 14 is decreased compared to the B-value of the conventional press fitting element, labeled 14'.

 Atomic ORME and S-ORME States of the Transition Group Elements
As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.

To resume, the transition group elements with their superdeformed "soft" nuclei all resonating to a single frequency, in their high spin low energy state, becoming a wave flow of light in a resonant unified entity, are a resonance coupled system of quantum oscillators, harmonically coupled in two dimensions.
