87: Charge It Up
from The History of Chemistry · host Steve Cohen
We hear of an unusual idea that appeared in the 1970s: that metals can become anions and gain electrons! These are the alkalide compounds, first discovered in 1974. Such compounds are anions of the alkaline metals, often combined with crown ethers. The second, related topic in this episode is that of solvated electrons, where electrons sit in the spaces between molecules. These compounds are the electrides. Finally, we touch on ionic liquids--not water, but liquids that are primarily ionic in nature, at or near room temperature. All of these topics ramped up in research popularity in the 1970s and 1980s.
