ABSTRACT Johan Gadolin (1760-1852), considered the father of Finnish chemistry, was one of the leading chemists of the second half of the 18th century and the first half of the 19th century. His life and scientific achievements were described in the literature published between the 19th and 21st centuries. The purpose of this paper is to familiarize readers with the important events in the life of Gadolin and his research activities, in particular some of his research results, as well as his selected publications.

But when we speak about false elements – in the aftermath of the celebrations marking this year, – we are greeted most warmly, but with some puzzlement, as to how it came to mind to celebrate “Mendeleev’s creature” in such a peculiar way, that is, by commemorating elements that never existed.

[120 pages] WESTON personnel collected six sediment samples (including one environmental duplicate sample) from five locations along the surface water pathway of the Canadian Radium & Uranium Corp. (CRU) site in May 2014. The sediment samples were analyzed for Target Analyte List (TAL) Metals and Stable Lead Isotopes. 1. TAL Lead Interpretation: In order to quantify the significance for Lead, Thallium and Mercury the following was performed: 1. WESTON personnel tabulated all available TAL Metal data from the May 2014 Sediment Sampling event. 2. For each analyte of concern (Lead, Thallium, and Mercury), the highest background concentration was selected and then multiplied by three. This is the criteria to find the significance of site attributable release as per Hazard Ranking System guidelines. 3. One analytical lead result (2222-SD04) of 520 mg/kg (J) was qualified with an unknown bias. In accordance with US EPA document “Using Data to Document an Observed Release and Observed Contamination”, 2222-SD03 lead concentration was adjusted by dividing by the factor value for lead of 1.44 to equal 361 mg/kg.

New power-plant construction has begun and the country is returning to full confidence in nuclear power as the Fukushima incident is placed in perspective. India, Africa and South America have recently emerged as serious exploration targets with numerous projects offering considerable merit in terms of size, grade, and mineability. During the period, the Chairman traveled to Columbus, Ohio to make a presentation to members of the Ohio Geological Society on the status of the uranium and nuclear industry in general (More).

    Redis co very of the Elements The Rare Earth s–The Beginnings I I I James L. Marshall, Beta Eta 1971 , and Virginia R. Marshall, Beta Eta 2003 , Department of Chemistry, University of North Texas, Denton, TX 76203-5070, [email protected] 1 Rare earths —introduction. The rare earths Figure 1. The “rare earths” are defined by IUPAC as the 15 lanthanides (green) and the upper two elements include the 17 chemically similar elements of the Group III family (yellow). These elements have similar chemical properties and all can exhibit the +3 occupying the f-block of the Periodic Table as oxidation state by the loss of the highest three electrons (two s electrons and either a d or an f electron, well as the Group III chemical family (Figure 1). depending upon the particular element). A few rare earths can exhibit other oxidation states as well; for These elements include the 15 lanthanides example, cerium can lose four electrons —4f15d 16s 2—to attain the Ce +4 oxidation state. (atomic numbers 57 through 71, lanthanum through lutetium), as well as scandium (atomic number 21) and yttrium (atomic number 39). The chemical similarity of the rare earths arises from a common ionic configuration of their valence electrons, as the filling f-orbitals are buried in an inner core and generally do not engage in bonding. The term “rare earths” is a misnome r—these elements are not rare (except for radioactive promethium). They were named as such because they were found in unusual minerals, and because they were difficult to separate from one another by ordinary chemical manipula - tions.
