										Sol. (a) Ti4+ > Min7+ is the correct order of size due to  lower positive charge on Ti4+.

(b) 37CI– = 37CI– : Isotopes with same charge have same size because isotopes differ in compositions of nuclei which do not affect the atomic/ionic radius.
(c) K+ <$1$2> P5+ is the correct order. For the same elements, lower the positive charge, larger the ions.
