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

Question:

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

1. $\mathrm{Cr}<\mathrm{Fe}<\mathrm{Co}<\mathrm{Cu}<\mathrm{Zn}$

2. $\mathrm{Cr}<\mathrm{Zn}<\mathrm{Co}<\mathrm{Cu}<\mathrm{Fe}$

3. $\mathrm{Zn}<\mathrm{Cu}<\mathrm{Co}<\mathrm{Fe}<\mathrm{Cr}$

4. $\mathrm{Zn}<\mathrm{Cr}<\mathrm{Fe}<\mathrm{Co}<\mathrm{Cu}$

Correct Option: , 4

Solution:

Fact Based

Density depend on many factor like atomic mass. atomic radius and packing efficiency.
