Which one of the following metals has the highest density?

Among the four metals given, Platinum has the highest density of 21.45 g/cm³, making it one of the densest naturally occurring elements on Earth. Platinum is a rare, precious, silvery-white metal that is remarkably heavy — a cube of platinum the size of a tennis ball would weigh as much as a large brick. Its exceptional density, combined with its resistance to corrosion and high melting point, makes platinum one of the most valuable and industrially important metals in the world.

• Platinum Density: 21.45 g/cm³ — one of the heaviest naturally occurring metals on Earth
• Gold Density: 19.32 g/cm³ — very dense but still significantly lighter than platinum
• Lead Density: 11.34 g/cm³ — commonly assumed to be very heavy but much lighter than both gold and platinum
• Iron Density: 7.87 g/cm³ — lightest among the four options given, despite being one of the most abundant metals
• Industrial Use: Platinum's exceptional density and corrosion resistance make it invaluable in catalytic converters, jewellery, laboratory equipment, and fuel cells
