Review of the Periodic Table of Elements (30 to 118), Bedtime Sleepy Science
from Lights Out Library: Sleep Documentaries · host Olimpia Pérez
In this science talk for bedtime, I review the periodic table of the elements methodically and explain in simple terms plenty of phenomena and concepts about chemistry and physics (for example in this episode: metalloids, alpha and beta decay, Xenon poisoning of nuclear reactors...) as well as the industrial and economic relevance of some of these elements. For tonight, we continue with elements 30 to 118, including zinc, arsenic, rhodium, silver, tungsten, platinum, gold, mercury, lead, uranium and plutonium. This podcast is entirely scripted and recorded by real people, it includes no AI, and mid-roll ad breaks are turned off so that you can relax without interruption.
