Statement I : `Zn^(2+)` is diamagnetic
Statement II : The electrons are lost from 4s orbital to from `Zn^(2+)`

(A) Zn^(+2) is diamagnetic (R) The electrons are lost from 4s orbital to form Zn^(+2)

(a). Assertion (A) is true, Reason (R) is also true, Reason (R) is the correct explanation for assertion (A). (b). Assertion (A) is true, Reason (R) is true, Reason (R) is not the correct explanation for Assertion (A). (c). Assertion (A) is true, Reason (R) is false. (d). Assertion (A) is false, Reason (R) is true. Q. Assertion (A): Zn^(2+) is diamagnetic. Reason (R): The electrons are lost from 4s-orbital to form Zn^(2+) .

Assertion : Fe^(2+) has 3de electronic configuration. Reason : Electrons are lost from 4s-orbital to form Fe^(2+) ion.

This question has statement I and Statement II. Of the four choices given after the statements, choose the one that best describes the two Statements. (1) Statement-I is true, Statement-II is true, Statement-II is a correct explanation of Statement-I (2) Statement-I is true, Statement-II is true,Statement-II is not a correct explanation of Statement-I (3)Statement-I is a true , Statement-II is false (4) Statement-I is false, Statement-II is true Statement-I : B_2 molecule is diamagnetic. Statement-II: The highest occupied molecular orbital is of pi -type.

Statement-1:Dipositive zinc exhibits diamagnetism due to loss of two electrons from 3d-orbital of neutral atom. Statement-2:The electronic configuration of zinc (Z=30) is [Ar]^(18)3d^10 4s^2

Why Zn^(2+) is diamagnetic whereas Mn^(2+) is paramagnetic ?
