the chloride ion (Cl−), the argon atom (Ar), and the potassium ion (K+) have 18 electrons in closed-shell configurations and are chemically quite stable. The number of electrons present in the neutral atomsconstitutingthe relatively unreactive noble gases exactly correspond to theatomicmagic...
Argon is isolated on a large scale by the fractional distillation of liquid air. It is used in gas-filled electric light bulbs, radio tubes, andGeiger counters. It also is widely utilized as an inert atmosphere for arc-welding metals, such asaluminumandstainless steel; for the production and...
Eighteen is the atomic number of argon. Group 18 of the periodic table is called the noble gases. The 18-electron rule is a rule of thumb in transition metal chemistry for characterizing and predicting the stability of metal complexes.
