Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R)
Assertion (A): The first ionization enthalpy of series elements is more than that of group 2 metals
Reason (R): In 3d series of elements successive filling of d-orbitals takes place.
In the light of the above statements, choose the correct answer from the options given below :
Assertion (A): The first ionization enthalpy of series elements is more than that of group 2 metals
Reason (R): In 3d series of elements successive filling of d-orbitals takes place.
In the light of the above statements, choose the correct answer from the options given below :
Multiple Choice Options
- A Both (A) and (R) are true and (R) is the correct explanation of (A)
- B (A) is true but (R) is false
- C Both (A) and (R) are true but is not the correct explanation of (A)
- D (A) is false but (R) is true
Step-by-Step Verified Solution
From Sc to Mn ionization energy is less than that of Mg.
Reason (R) : The statement "In series of elements successive filling of -orbitals takes place" is indeed true. It describes the characteristic of series elements where there is successive filling of orbitals as we move across the period.
