Given below are two statements:
Statement I : The decrease in first ionization enthalpy from B to Al is much larger than that from Al to Ga.
Statement II : The d orbitals in Ga are completely filled.
choose the most appropriate answer from the options given below
Text Solution
Verified by ExpertsThe correct answer is:
B
The first ionization energies (as in NCERT) are as follows:
B: 801 kJ/mol
Al: 577 kJ/mol
Ga: 579 kJ/mol
Ga : [Ar]3d 10 4s 2 4p 1
