Identify the formula of the corresponding hydrideof a nonmetal 'X' whi

1.	Identify the formula of the corresponding hydrideof a nonmetal 'X' which attainsoctet by gaining twoelectrons.
Answer» XH `XH_(3)` `XH_(4)` `XH_(2)` Solution :X ATTAINS OCTET after gaining two electrons . HENCE , the valency is 2(X2) and valency of hydrogen is 1.`X^(-2)H^(+1)rArrXH_(2)`
