Periodic Table of Elements (13 to 29)

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: the timeline of the discovery of elements, why there is quite a lot of iron in the universe, endothermic and exothermic fusions...) as well as the industrial and economic relevance of some of these elements. For tonight, we continue with elements 13 to 29: aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, and copper.
