Ionic radii of (1) Ti^(4+) lt Mn^(7+) (2) ""^(35)Cl^(-) lt ""^(37)Cl

1.	Ionic radii of (1) Ti^(4+) lt Mn^(7+) (2) ""^(35)Cl^(-) lt ""^(37)Cl^(-) K^(+) gt Cl^(-) Pt^(3+) gt P^(3+)
Answer» Solution :(1) Since `TI^(4+) and Mn^(7+)` are isoelectronic, hence, `Mn^(7+) lt Ti^(4+)`. (2) `""^(35)CL^(-) and ""^(37)Cl^(-)` are isotopes, hence,`""^(35)Cl cong ""^(37)Cl^(-)` (3) Again, `K^+ and Cl^(-)` are isoelectronic, hence, `K^+ lt Cl^(-)` (4) `P^(3+)` has 12 electrons and 15 protons, while `P^(5+)` has 10 electrons and 15 protons, hence `P^(5+) lt P^(3+)`
