Episode notes
Mercury's Unique Liquid State
- Mercury is the only metal liquid at room temperature due to unique atomic structure.
- Its name means "watery silver," reflecting this unusual property known to ancients.
Kelly's Mercury Necklace Story
- Kelly Weinersmith wore a necklace with a vial of mercury as a child in the 90s.
- She recalls the luck involved in never breaking it and being exposed to mercury.
Melting and Bond Strength
- Melting occurs when bonds between atoms loosen enough to allow flow.
- Liquids have weak intermolecular bonds allowing atoms to slide past each other.
