A. Platinum
B. Copper
C. Steel
D. Osmium
Check Answer
The correct answer is: D) Osmium.
Osmium is a chemical element with the symbol Os and atomic number 76. It is a rare, hard, bluish-white metal that is known for its high density and strength. Osmium is the densest naturally occurring element on Earth, with a density of 22.59 g/cm3 at room temperature. This is about twice the density of lead, and slightly denser than iridium, which is the second densest element.
Osmium is often used as an alloying element in hardening other metals, such as platinum and steel. It is also used in the manufacture of electrical contacts and other electrical components, due to its high melting point and resistance to wear and corrosion.
