Revision Quizzes Looking at Ions We've talked about ions before. Layered oxides offer a natural starting point in the search for electrodes for sodium (Na)-ion batteries. 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. When sodium reacts with non-metals 11 electrons (green) bind to the nucleus, with a single, relatively unstable electron in the outer shell (ring). of all atoms can be found in the data booklet. The compounds that have ionic bonds are commonly called salts. loses its outer      The low-temperature structure of NVPF [Na3V2 (PO4)2F3] solved in this work.
