Question
Which is the correct order of the following elements with respect to their density? –3 (A) Cr < Zn < Co < Cu < Fe (B) Zn < Cu < Co < Fe < Cr (C) Zn < Cr < Fe < Co < Cu (D) Cr < Fe < Co < Cu < Zn
Answer: C) ZN < CR < FE < CO < CU
💡 Solution & Explanation
According to NCERT data, the densities (in g cm ) are: Zn = 7.1 Cr = 7.19 Fe = 7.8 Co = 8.7 Cu = 8.9
