The pair of elements with same electronegatively and stardard oxidation potential are

Answer»

Mg and CA
Ca and Sr
Ca and Ba
Ba and Be

Solution :Sr has small size than expected due to POOR SHIELDING of d - orbitals, so both `Ca^(+2) and Sr^(+2)` have same HYDRATION energy there by sameoxidation potential.
