Consider the following statements :
(I)Rutherford name was associated with help the development of periodic table
(II)A metal M having electronic configuration `1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^10, 4s^1` is d-block element.
(III)Diamond is not an element
(IV)The electronic configuration of the most electronegative element is `1s^2, 2s^2, 2p^5`
Select the correct option from the given codes 1

Options

A. I,II,IV
B. I,II,III,IV
C. II,IV
D. I,II,IV

Answer

C

Explanation

(ii)The d-block elements have general electronic configuration [noble gas] `(n-1)d^(1-10)ns^(1-2)`.It is configuration of copper which belongs to d-block and group number `11^(th)`
(IV)This is the configuration of F (electronegativity=4.0) which belongs to p-block and group number `17^(th)`
