Is copper heavy or light?
The earliest known metals—common metals such as iron, copper, and tin, and precious metals such as silver, gold, and platinum—are heavy metals. From 1809 onward, light metals, such as magnesium, aluminium, and titanium, were discovered, as well as less well-known heavy metals including gallium, thallium, and hafnium.
What is the heaviest material by volume?
Osmium is the world’s heaviest material and is twice the density of lead, but it is rarely used in its pure form due to its highly toxic and volatile nature.
