Electronic configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 2 5s 2 >> Back to key information about the elementBack to key information about the element In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. Electron configuration for Thorium. Electron configuration: 6d27s2 Thorium was discovered (1828) by Swedish chemist Jöns Jacob Berzelius. Here Are The Chemical Properties Of Thorium. Zirconium Electronic configuration. Atomic Structure of Thorium. There are 118 elements in the periodic table. Help! In the case of Thorium the valence electrons is 4. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. State at 20°C – Solid. In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Thorium is [Rn] 6d2 7s2. Possible oxidation states are +4. Melting point - 1750°C, 3182°F,2023K Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. Apparently, electron configuration for Thorium is [Rn] 6d2 7s2. Thorium-232 first absorbs a neutron, creating thorium-233, which decays to protactium-233 over the course of about four hours. It is silvery white but turns gray or black on exposure to air. Electron Configuration Chart for All Elements in the Periodic Table. Electron configuration The arrangements of electrons above the last (closed shell) noble gas. A valence electron is an outer shell electron and may participate in the formation of a chemical bond. Unabbreviated electronic configuration of neutral Thorium. Post by Hee Sang Kim 3L » Sat Oct 10, 2015 1:56 am . Electron Affinity. Thorium atomic radius is 180 pm, while it's covalent radius is N/A. ... electron configuration of gaseous atomic state [Rn]6d 2 7s 2: The electron configuration of thorium is [Rn]6d27s2. Electron Affinity of Thorium is — kJ/mol. Top. Group - Actinides . However, I thought it would be [Rn] 5f1 6d1 7s2 since its on the F block right after the first 6d element (Actinium). Block – f. Atomic number – 90. But thankfully this wasn't so. Thorium 232 has 90 protons and electrons and 142 neutrons. Now let's check the facts about Thorium... Thorium Overview Thorium Valence Electrons 4 Atomic Number 90 Electron Configuration Number of Neutrons Melting Point Boiling Point Date of Discovery Crystal Structure. Electronegativity of Thorium is 1.3. Chem_Mod Despite the anomalous electron configuration for gaseous thorium atoms, metallic thorium shows significant 5f involvement. Ok but how many valence electrons does an atom of Thorium have? Period – 7. 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s2 6p6 6d2 7s2.
