1.	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
Answer» I,II,IV I,II,III,IV II,IV I,II,IV Solution :(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)`
