Vedclass · Answer

(C) In the $3d$ transition series,density generally increases from left to right as atomic mass increases and atomic volume decreases.However,$Zn$ has a lower density than $Cr$ because of its larger atomic size due to fully filled $d$-orbitals.The density values (in $g/cm^3$) are: $Zn (7.13) Therefore,the correct order is $Zn < Cr < Fe < Co < Cu$.

What is the correct order of the following elements with respect to their density?
