This element is a noble gas. Where is it located in the periodic table? A. In group 18 B. In group 17 C. In group 16 D. In group 15 相关知识点: 试题来源: 解析 A。稀有气体在周期表中的第十八族。第十八族元素为稀有气体,化学性质非常稳定。
They were also clustered under Group 0 in the old periodic table because scientists believed that the gases have zero valence electrons in their outer shell. This was later proven to be untrue when some noble gas compounds were discovered.3. The gases are elements, which share similar ...
The last group of elements in the periodic table consists of the noble gases, which have solid phases in the fcc structure at low temperatures. The total energy plots give the fcc as the ground state for all these elements in agreement with experiment. These materials become metallic at large...

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.
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...
The position of elements A,B,C,D and E in the periodic table are shown below: Group 1 Group 2 Group 17 Group 18 D B C A E a State which are metals, non metals and noble gas in this table. b State which is the most reactive i m
In 1913 the Danish physicist Niels Bohr proposed that the electrons in atoms are arranged in successive shells having characteristic energies and capacities and that the capacities of the shells for electrons determine the numbers of elements in the rows of the periodic table. On the basis of ...
and having low chemical reactivity.Noble gases include hepum,neon,argon,krypton,xenon and radon.These are all found in Group 18,in the right most column of the periodic table.If you look at the periodic table,you will notice that these elements are the only ones which do not have a ...
