It is now known, however, that several of these elements are quite abundant on Earth and in the rest of the universe, so the designation rare is misleading. Although only the noble-gas atoms possessed this arrangement, it was the condition toward which the atoms of all other elements tended in their chemical bonding. Ramsay and his coworkers searched for related gases and by fractional distillation of liquid air discovered krypton, neon, and xenon, all in 1898. These values were determined using several different methods.

The atomic number of each element increases by one, reading from left to right. This configuration is also known as the inert gas or noble gas configuration because it is very stable and does not readily form chemical bonds with other atoms. A breathing mixture of 30% xenon and 30% krypton is comparable in effectiveness for CT to a 40% xenon fraction, while avoiding the unwanted effects of a high partial pressure of xenon gas. Krypton-83 has application in magnetic resonance imaging (MRI) for imaging airways. Elements in group __________ have a np electron configuration in the outer shell. Screened from the nucleus by intervening electrons, the outer (valence) electrons of the atoms of the heavier noble gases are held less firmly and can be removed (ionized) more easily from the atoms than can the electrons of the lighter noble gases. The s orbital is always represented by an S, p orbitals are represented by P, d orbitals are represented by D, and f orbitals are represented by F.
