Electron Configuration: 1s 2 2s 2 p 6 3s 2 p 6 d 10 4s 2 p 6 d 10 f 5 5s 2 p 6 6s 2; Half of the distance between two atoms within a single covalent bond. These are roughly the size of a drawing pin and are used for pacemakers, guided missiles and radios. The β-phase is body-centred cubic with a = 4.10 Å (estimated) at 890 °C (1,634 °F). Copyright 1995 - 2021 Kenneth L Barbalace (. It is given by the ratio of the shear stress to the shear strain. High = substitution not possible or very difficult. High = substitution not possible or very difficult. You may not further copy, alter, distribute or otherwise use any of the materials from this Site without the advance, written consent of the RSC. Period Promethium, symbol Pm, has a Simple Hexagonal structure and Silver color. Element density: 7.26 g/cm 3. Instead the element's beta radiation has been used in industry to measure the thickness of materials, and the isotope promethium 147 has been used in nuclear batteries. Finally element 61 was produced in 1945 by Jacob .A. Looking Good, Feeling Bad; or, What's the Problem with Perc? So a provider of portable and long life power named after the bringer of fire. In 1902 Branner predicted the existence of an element between neodymium and samarium, and this was confirmed by Moseley in 1914.

In nuclear batteries, promethium comes about as close as we've ever got to a portable nuclear powered energy source. Comprehensive information for the element Promethium - Pm is provided by this page including scores of properties, element names in many languages, most known nuclides and technical terms are linked to their definitions. Each allotrope has different physical properties.
