Group VIIIA elements gases

Ans. Group VIIIA element (also referred to as an inert gas or noble gas)... 

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... 

Xenon is a noble gas. The term noble gas is used to describe the elements in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Noble gas suggests a group of elements that is too far above other elements to react with them. The noble gases are also called the inert gases. That term has the same meaning. The noble gases react with other elements only under very unusual circumstances.

Not only is ununoctium expected to be a gas, but it should also be a nonmetal when discovered. It is located at the bottom of group 18 (VIIIA) in the periodic table and could be expected to have some of the characteristics of it neighbors above it in this group. When first and erroneously reported as being discovered, it was said to have 118 protons and 175 neutrons in its nucleus for an atomic mass number (amu) of 293, which would make it the heaviest of the yet-to-be discovered elements.
