Various physical properties of eka-emanation (element 118) and emanation (element 86) are derived from van der Waal's theorem of corresponding states for noble gases. The properties include crystal lattice parameters and unit cell dimensions, density and atomic volume of solid and liquid from 0掳...
Physical, Chemical and Nuclear Properties of Radon: An Introduction Radon is the heaviest of all noble gases and has a total of 36 isotopes ranging from 193Rn to 228Rn all of which are radioactive. Over a large portion of the past 115 years since its first discovery in 1900, radon has ...
noble gas elec tron configuration of 2,8 and a charge of -1.By looking at this and seeing that xenon is pretty far down in the group we can see that it will have similar properties to the other noble gases but not exact which means that it might not be as inert as the others.So...
