Why were the compounds
of noble gases discovered late
? Why do noble gases
form
compounds
only
with oxygen and fluorine
?
1. Noble gases were discovered later than other elements, because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate...

why were the compounds of nobel gasses discovered late. why do nobel gasses form compounds with oxygen and fluorine
Noble gasses have full valence shell – 8 paired electrons (this value correspond to number of element’s Group in Periodical table; 8 Group is the last Group in Periodical table)....

Why were the compounds of noble gases discovered late? Why do noble gases
form compounds only with oxygen and fluorine?
noble gases (He, Ne, Ar, Kr, Xe, Rn) are the elements with the fully filled outer shell of valence electrons, so that under normal conditions their atoms do not need...

Unlike Organosodium And Organopotassium Compounds,organolithium Compounds Are Soluble In Hydrocarbon And Other Non Polar Solvent
In order for the salt to dissolve, the lattice energy holding the atoms (ions) together must be overcome. That is to say, the coulombic forces must be overcome and the...

Antimony pentafluoride, SbF5, reacts with XeF4 and XeF6 to form ionic compounds, XeF_3^+ SbF_6^- and XeF_5^+ SbF_6^-. Describe the geometries of the cations and anion in these two compounds.
Cations are [XeF3]+ [XeF5]+...Hence first geometry of these two are...The geometry of [XeF3]+ ion is bent T-shaped.Because the central Xe atom has 2 lone pairs and 3 bond pairs of electrons. The electron pair geometry is...
