In this science talk for bedtime, I review the periodic table of the elements methodically and explain in simple terms plenty of phenomenons and concepts about chemistry and physics (the structure of atoms, valence and reactivity, isotopes, allotropes, ionic compounds, the definitions of metals, metalloids or noble gases, radioactivity...) as well as the industrial and economic relevance of some of these elements.
