Answer 1

Answer:

2) Polarizability of S²‾ is higher than

please mark me as branliest

Answer 2

The correct statements are options 1, 2, and 3.

• Despite the fact that the magnitude of charge for both the Sulphur ion (S²‾) and the Selenium ion (Se²‾) is the same, Se²‾ is larger than S²‾.
• Hence, the polarizability of an anion increases with its size, Se²‾ is more polarizable than S²‾ and the option (1) is correct.
• Among S²‾ and chlorine ion (Cl‾ ) which have the same magnitude of charge, S²‾ is more polarizable since it is larger in size than Cl ‾.
• The size and the magnitude of the negative charge of Phosphorus ion (P³‾) is more than S²‾ and hence it is more polarizable.
• The polarizability of an anion is directly proportional to its magnitude of negative charge.
• Among Oxygen ion (O²‾) and S²‾ which have the same magnitude of charge, S²‾ is more polarizable since it is larger in size than O²‾. Hence, option (4) is not valid.
• Polarizability is the tendency of molecules to produce induced electric dipole moments when exposed to an electric field.
