Suggest reason why only known binary compounds of noble gases are fluorides

Correct Answer is: (d)  Sound is transmitted by particles (atoms or molecules) in a solid, liquid or gas colliding with each other. It is a wave which is created by vibrating...

Kössel’s explanation of chemical bonding: Noble gases separate the highly electronegative halogens and the highly electropositive alkali metals. Halogens can form negatively charged ions by gaining an electron. Whereas alkali metals can form positively...

[Hint : (i) According to Fajan’s Rule, bigger ions are more polarized than the smaller ions by a particular cation. (ii) ClO4 - is more resonance stabilized than SO4 2- since dispersal of negative charge...

[Hint : Because noble gases are stabilized by weak van der Waal’s forces.]

[Hint : (i) Due to their electron conflguration. (ii) Due to its less solubility in blood. (iii) Due to its high ionization enthalpy.]

(i) Different elements discovered in different times were found to possess different physical and chemical properties. But, it was difficult to study all the information or properties of these elements....

(d) He, Ne, Ar, Kr, Xe, Rn

(d) Electronic configuration of He is 1s2

(a) Ionisation energy decreases as we move away from nucleus due to less electrostatic attraction between electrons and nucleus

(b) (i) and (ii)
