Facts blog number 32! Hope you enjoy this metals edition!
1. Mercury melts at -37 degrees Fahrenheit, the lowest melting point of any metal.
2. Tungsten has the highest melting temp of any metal at 6,192 degrees Fahrenheit.
3. The human body needs eight different metals for healthy bodily function: copper, zinc, sodium, calcium, potassium, manganese, and magnesium. There are other metals the human body uses for different things, but not as prominently.
4. Up until the Middle Ages, there were only seven known metals: Bronze, iron, gold, copper, silver, lead, and mercury.
5. Ever noticed many handrails and doorknobs on public places are made of brass? This is because brass has antibacterial properties.
6. If two pieces of uncoated metal touch in space, they become permanently stuck together. It doesn’t happen on Earth because the atmosphere puts a thin layer of oxidation between the surfaces. The oxidized layer actually acts as a barrier, preventing adherence.
7. Indium is a nontoxic metal that is so soft, it can be molded by hand.
8. Osmium is considered the rarest precious metal on earth - only a few tonnes a year are mined compared to around 2700 tonnes of gold every year.
9. Arsenic is a metal.
10. Gallium melts in your hand.
