An element A decays into element C by a two step process A --> B + 2 He 4 B ---> C + 2e - Then (a) A and C are isotopes (b) A and C are isobars (c) A and B are isotopes (d) A and B are isobars



An element A decays into element C by a two step process


A --> B +2He4


B ---> C + 2e-


        Then


(a)    A and C are isotopes


(b)    A and C are isobars


(c)    A and B are isotopes


(d)    A and B are isobars

(a)

From eqn. (ii), B has 2 units of charge more than C.

From eqn. (i), A loses 2 units of charge by emission of alpha particle. Hence,

A and C are isotopes as their charge no. is same.
