Group VIIIA elements electron configurations

The p block includes elements of groups 13 (IIIA) through 18 (VIIIA). Electron configurations of the p block atoms take the general form ns np°, where a represents a value ranging from 1 to 6. Because the three p orbitals can hold a maximum of six electrons, the p block elements span six groups. 

The inner electrons, those below the valence electrons, are arranged as is the noble gas element (Group VIIIA) before the element under consideration. If we were to consider titanium (Ti, Z = 22), the electron configuration could be expressed as [ Ar 13c/24.s2. Note that, although the Aufbau principle indicates the 4s filling before the 3d, it is common practice to present the electron configuration in numerical order with respect to n, rather than the... 

Because the elements on the far right edge of the periodic table, Group VIIIA, the noble gases, have electronic configurations that are uniquely stable, they are the only elements whose symbols... 

What is the common feature of the electron configurations of elements in Group VIIIA (18) ... 

Rare gases are those elements in Group VIIIA of the periodic table helium, neon, argon, krypton, xenon, and radon. They are not necessarily rare, however, and are also called the inert or noble gases. Due to their electron configurations, helium, neon, and argon are extremely nonreactive, while others undergo some reactions. 

In our discussions of bonding, we pointed out the relative stability of the electron configurations of the Group VIIIA noble gases. For many years, it was thought that because the atoms of these elements had completed octets, Ihe noble gases would be completely unreactive. Consequently, these elements were known as inert gases. Compounds of krypton, xenon, and radon have since been prepared, however, so (he term is not quite appropriate.
