The elements in the last column or group of theperiodic tableshare special properties. These elements arenoble gases, sometimes called inert gases. Atoms belonging to thenoble gas grouphave completely filled their outer electron shells. Each element is non-reactive, has high ionization energy,electro...

The noble gases represent group 0 in the Periodic Table of the elements. As their outer electron layers are complete (noble gas configuration) they are quite elementsinertinert and have no tendency todoi:10.1007/1-4020-4496-8_107Thomas Staudacher...
as we move through each period on the periodic table, the elements increase in the number of electrons they contain. Furthermore, we can make predictions about their melting and boiling points. The element with the lowest boiling point and melting point is at the top of group, helium, and ...
noble gas- any of the chemically inert gaseous elements of the helium group in the periodic table argonon,inert gas chemical element,element- any of the more than 100 known substances (of which 92 occur naturally) that cannot be separated into simpler substances and that singly or in combinati...
They werealso listed under Group 0 in theold periodic table because scientists believed that the gases have zero valence(价)electrons in their outer shell. This was later proven to be untrue when somenoble gas compounds were discovered. 3 Thegases are elements, which share similar properties. ...
The atomic sizes of the noble gas elements increase from top to bottom in the Periodic Table, and the amount of energy needed to remove an electron from their outermost shell, the ionization energy, decreases in the same order. Within each period, however, the noble gases have the largest ...
inert gas inert gasornoble gas,any of the elements in Group 18 of theperiodic table. In order of increasing atomic number they are:helium,neon,argon,krypton,xenon, andradon. They are colorless, odorless, tasteless gases and were once believed to be entirely inert, i.e., forming no chemica...
Inert Gases don't readily react with other elements; Noble Gases are a specific group of inert gases in the periodic table's Group 18.
