Electronic configuration of some elements is given

Question:

Electronic configuration of some elements is given in Column I and their electron gain enthalpies are given in Column II. Match the electronic configuration with electron gain enthalpySolution: V. Assertion and Reason TypeIn the following questions, a statement of Assertion (A) followed by a statement of the reason (R) is given. Choose the correct option out of the choices given below each question.46. Assertion (A): Generally, ionisation enthalpy increases from left to right in a period.Reason (R): When successive electrons are added to the orbitals in the same principal quantum level, the shielding effect of the inner core of electrons does not increase very much to compensate for the increased attraction of the electron to the nucleus. 

(i) The assertion is correct statement and reason is the wrong statement. 

(ii) Assertion and reason both are correct statements and reason is the correct explanation of assertion. 

(iii) Assertion and reason both are wrong statements. 

(iv) The assertion is wrong statement and reason is the correct statement.

Solution:

Option (ii)  Assertion and reason both are correct statements and reason is the correct explanation of assertion  is correct.
