The correct answer is
Osmium

Element Densities: Maximum Density Element

Density is defined as mass per unit volume. Comparing the densities of various elements helps identify which is the most compact.

Comparing Densities of Listed Elements

The approximate densities of the elements provided are:

Element Symbol Approximate Density ($\text{g/cm}^3$)
Lead Pb 11.34
Platinum Pt 21.45
Mercury Hg 13.53
Osmium Os 22.59

Maximum Density Identification

By comparing these values:

  • Osmium exhibits the highest density (22.59 $\text{g/cm}^3$).
  • Platinum has the second highest density (21.45 $\text{g/cm}^3$).
  • Mercury's density is 13.53 $\text{g/cm}^3$.
  • Lead has the lowest density among the options (11.34 $\text{g/cm}^3$).

Thus, Osmium is the element with the maximum density among the given choices.
