`S_(1):` Argon is used in arc welding of metals or alloys to provide an inert atomosphere.   `S_(2):" XeF_(2),XeF_(4)` and `XeF_(6)` are colourless crystalline solids and sublime readily at `298K`.   `S_(3):XeF_(2),XeF_(4)` and `XeF_(6)` are readily  hydrolysed.   `S_(4): ` Xenon fluorides react with flourine ion acceptor to form cationic species and fluoride ion donors to form fluoro anions.
