What are the Heaviest Metals?
The heaviest metals are typically defined by their high atomic weights and densities. Some of the most commonly recognized heavy metals include:
- Osmium
- Iridium
- Platinum
- Gold
- Tungsten
- Lead
- Uranium
These metals are not only heavy but also possess unique chemical properties that make them suitable for various applications. For instance, osmium and iridium are often used in high-performance applications due to their durability, while lead is widely recognized for its shielding capabilities against radiation.
How are Heaviest Metals Measured?
Heaviest metals are measured based on their density, which is defined as mass per unit volume. The standard unit for density is grams per cubic centimeter (g/cm³). Here are some examples of their densities:
| Metal | Density (g/cm³) |
|---|---|
| Osmium | 22.59 |
| Iridium | 22.56 |
| Tungsten | 19.25 |
| Gold | 19.32 |
| Lead | 11.34 |
| Uranium | 18.95 |
What are the Uses of Heaviest Metals?
The heaviest metals have diverse applications across various industries:
- Osmium and Iridium: Used in the manufacture of fountain pen tips, electrical contacts, and other applications requiring durability.
- Gold: Widely used in electronics, jewelry, and as a standard for monetary systems.
- Lead: Historically used in paints and plumbing, now primarily used for radiation shielding and batteries.
