General Properties and Reactions of The Actinides
Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft and malleable and has a high melting point. Thorium is an electropositive actinide whose chemistry is … See more Thorium is a moderately soft, paramagnetic, bright silvery radioactive actinide metal. In the periodic table, it lies to the right of actinium, to the left of protactinium, and below cerium. Pure thorium is very See more Formation Th is a primordial nuclide, having existed in its current form for over ten billion years; it was formed … See more Erroneous report In 1815, the Swedish chemist Jöns Jacob Berzelius analysed an unusual sample of gadolinite from … See more All but two elements up to bismuth (element 83) have an isotope that is practically stable for all purposes ("classically stable"), … See more A thorium atom has 90 electrons, of which four are valence electrons. Four atomic orbitals are theoretically available for the valence electrons to occupy: 5f, 6d, 7s, and 7p.
