Periodic Table

This chemistry video tutorial provides a basic introduction into the periodic table. It explains the difference between groups and periods. It covers the alkali metals, alkaline earth metals, transition metals, chalcogens, halogens, noble gases, lanthanides, and the actinides. It also discusses the difference between metals, metalloids, and nonmetals as well as their properties. It covers valence electrons, mass number, atomic number, chemical symbols, ionic charge, and other stuff.

[bluefirephoenix]

Fun fact:I memorized 1-50 of them I managed to memorized them 3 days I'm so proud to my science teacher who told us to memorize it for extra points although I forgot the name of the elements already I still can remember my passion to memorize the elements 😆

[and]

I actually can't understand chemistry without you teaching it. It has become my habit 😂
