JIPMER2016Chemistrys Block Elements
Beryllium differs in properties from other elements of its own group but shows resemblance with aluminium because of
Options
- Arelatively bigger ionic radius and high polarising power of Be
- Brelatively smaller ionic radius and high polarising power of Be
- Crelatively bigger ionic radius is the only reason behind this
- DNone of the above
Correct answer
B. relatively smaller ionic radius and high polarising power of Be
Step-by-step solution
Due to relatively smaller ionic radius and high polarising power, Be differs in properties from other elements of its own group. Polarising powers of Be ²⁺ and Al ³⁺ ions are almost the same, thus they show similarities in their properties.
