Electron configuration The arrangements of electrons above the last (closed shell) noble gas. 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 when an electron is added to the atom to form a negative ion. ... 2.2 Electron Configuration. Ionic Radius: Filling Orbital: Number of Electrons (with no charge): 107.

Bh + e – → Bh – – ∆H = Affinity = — kJ/mol To use electron affinities properly, it is essential to keep track of sign. Possible oxidation states are —. ... Bohrium is also special in another respect, as the first element to be synthesised by a cold - rather than hot - fusion process between two nuclei. Electron Configuration and Oxidation States of Bohrium. 7s 2.

An atom of Bohrium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Bohrium. 2.3 Atomic Radius. Look up properties, history, uses, and more.
