Atom with NR electrons
In Mechanical quantum and Physical atomic, one calls Atome with NR electron S, the equation of Schrödinger considering NR electrons " gravitant" around a core of Load Z. If Z = NR, it acts of an atom. If Z= N-k, it acts of a Anion of load - K. If Z = N+k, it acts of a Cation of load +k. The series is called Isoélectronique.
In addition, the chemical behavior of a Chloride Cl, Argon, and cation Potassium K+, notwithstanding their load is similar: very stable, they are quasi-inert chemically. As well in a crystal of Chloride potassium, the connection in the crystal is reduced it to an electrostatic attraction of " balls quasi-impénétrables" (this resulting from the Principle of exclusion of Pauli).
