Periodic Table: Hydrogen To Magnesium

In this science talk for bedtime, I review the following chemical elements methodically: hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, and magnesium. I also explain in simple terms plenty of phenomena and concepts about chemistry and physics (for example the structure of atoms, valence, reactivity, isotopes, allotropes, ionic compounds, and the definitions of metals).
