Although thorium (90Th) has 6 naturally occurring isotopes, none of these isotopes are stable; One isotope, Th, has a nuclear isomer (or metastable state) with a remarkably low . It is not immediately clear why the transition has not been found to be excited in a undulator light experiment. . EC: Electron capture. Thorium was discovered by Jöns Jacob Berzelius, a Swedish chemist, in Thorium is also used to coat tungsten filaments used in electronic devices. Beamline: discovery of nuclear transition could lead to better clocks However, the transition between the ground state of the thorium nucleus and atoms and the nuclei decay within 1 s, producing a cloud of electrons.

Atomic information and electron configuration of thorium Berzelius isolated thorium by first mixing thorium oxide found in the mineral with. Element Thorium (Th), Group 20, Atomic Number 90, f-block, Mass Sources, facts, uses Discovered by, Jöns Jacob Berzelius. Origin of the name Th, Th. Electron configuration, [Rn] 6d27s2, CAS number, Thorium was discovered () by Swedish chemist Jöns Jacob Berzelius. Synthetic isotopes have been prepared; thorium (7,year half-life), formed in the decay chain electron configuration of gaseous atomic state, [Rn] 6d27s2.

Thorium thorium: Synthetic isotopes have been prepared; thorium ( year half-life), formed in the decay chain originating in the synthetic actinoid . Thorium's properties, discovery, videos, images, states, energies, appearance and characteristics. Electron configuration: [Rn] 6d2 7s2. Density @ 20oC: . Thorium at Chemical Basic Information Number of Protons/ Electrons: Number of Th, years. Th Date of Discovery: What is thorium (element 90), its type, properties (atomic weight, melting point, density, atomic number, electron configuration), common uses, price, pictures. Thorium might be useful in the treatment of cancer and infectious diseases.
