size of which elements are as non bonded radis
Answers
Answer:
Atomic radius is ur answer......
Answer:
Mainly the NOBLE gases
Explanation:
In a particular period of the periodic table, the noble gases have the most desired and stable electronic configuration of either duplet or octet stabilities. They basically do not have any intrinsic coherent tendency to form compounds because both their ionsiation enthalpy and electon gain enthalpy are peculiarly stable. If two such molecules are brought nearer, one cannot nullify the probability of formation of a weak bond seperated by Vanderwaal's radii and Vanderwaal's force of attraction. This force predominates as a weak force in the influential zone of a single atom and the interatomic radii as a mutual interaction due to its presence.
However, the aforementioned phenomena of Vanderwaal's fragile interactions are possible only in some compounds of Krypton(Kr) among all the other noble gases. The noble elements like He, Ne, Ar have extensive and remarkably high non-tendencies to form any compounds due to such attractive forces. Exceptionally enough Xenon(Xe) is the only noble gas to show a deviation from the general trend and due to its accomodation capability and less ionisation potential it is known to form many of Bartlett & Clatharate compounds forming true covalent & dative bonds with O, F & even H, which exist naturally and can be synthesised(the first synthesised Xe compound was Xenon platinum hexaflouride[XePtF6]). Xe compounds ionise to form corressponding Xenate ions & shows all properties of other representative & transition elements. Practically helium, neon and argon are not yet discovered.
