WebAnswer (1 of 2): Group 18 elements are called inert gases or Noble gases because they are unreactive. They all have completely filled outer orbitals with 8 electrons except Helium with 2 electrons. Their general outer electronic configuration is ns2 np6 ( Helium 1s2). The valence electrons or ... WebApr 7, 2024 · Representative elements are those where the s and p orbitals are being filled, i.e., the elements that make up the s and p blocks – groups 1, 2 and 13-18. The elements in group 18 are noble gases and are unreactive. Due to this, some do not consider them to be representative elements, even though they are a part of the p block.
WebNoble gases are elements of group 8A, i.e., column 18 of the periodic table. They have filled valence shells and are thus chemically inert; however, xenon, krypton, and radon can react with oxygen and fluorine to form corresponding derivatives at tremendous conditions. ...
