  2. Terbium - Wikipedia

    en.wikipedia.org/wiki/Terbium

    hexagonal close-packed (hcp) (hP2) Terbium is a chemical element; it has the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable and ductile. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas.

  3. Electron configurations of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Electron_configurations_of...

    This page shows the electron configurations of the neutral gaseous atoms in their ground states. For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell. For phosphorus (element 15) as an example, the concise form is [Ne] 3s 2 3p 3.

  4. Electron configuration - Wikipedia

    en.wikipedia.org/wiki/Electron_configuration

    Electron configuration. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s2 2s2 2p6, meaning that the 1s, 2s, and 2p subshells are occupied by ...

  5. Periodic table (electron configurations) - Wikipedia

    en.wikipedia.org/wiki/Periodic_table_(electron...

    Grayed out electron numbers indicate subshells filled to their maximum. Bracketed noble gas symbols on the left represent inner configurations that are the same in each period. Written out, these are: He, 2, helium : 1s 2. Ne, 10, neon : 1s 2 2s 2 2p 6. Ar, 18, argon : 1s 2 2s 2 2p 6 3s 2 3p 6.

  6. Isotopes of terbium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_terbium

    Isotopes of terbium (65Tb) Naturally occurring terbium (65 Tb) is composed of one stable isotope, 159 Tb. Thirty-seven radioisotopes have been characterized, with the most stable being 158 Tb with a half-life of 180 years, 157 Tb with a half-life of 71 years, and 160 Tb with a half-life of 72.3 days. All of the remaining radioactive isotopes ...

    Fullmetal Alchemist. (TV series) Fullmetal Alchemist (Japanese: 鋼の錬金術師, Hepburn: Hagane no Renkinjutsushi) is a Japanese anime television series loosely adapted from the original manga series of the same name by Hiromu Arakawa. Comprising 51 episodes, it was produced by the animation studio Bones for Mainichi Broadcasting System and ...

  8. Hassium - Wikipedia

    en.wikipedia.org/wiki/Hassium

    The Hs 2+ ion is expected to have an electron configuration of [Rn] 5f 14 6d 5 7s 1, analogous to that calculated for the Os 2+ ion. [4] In chemical compounds , hassium is calculated to display bonding characteristic for a d-block element, whose bonding will be primarily executed by 6d 3/2 and 6d 5/2 orbitals; compared to the elements from the ...

  9. Chalcogen - Wikipedia

    en.wikipedia.org/wiki/Chalcogen

    Highly metal-rich metal chalcogenides, such as Lu 7 Te and Lu 8 Te have domains of the metal's crystal lattice containing chalcogen atoms. While these compounds do exist, analogous chemicals that contain lanthanum , praseodymium , gadolinium , holmium , terbium , or ytterbium have not been discovered, as of 2008.
