Being able to read the Periodic Table provides you with a “legal cheat sheet”. Therefore, Episode 3 recaps the set-up of the periodic table and how to read it.Dimitri Mendeleev is known as the Father of the Periodic Table (1:25). He arranged the elements with increasing relative atomic mass as well as elements with similar properties together (2:25). Today’s periodic table arranges elements by increasing atomic number (3:13). The horizontal rows in the periodic table are called periods, vertical columns in the periodic table are called families or groups (3:40). Several groups are described in greater detail: alkali metals, alkaline earth-metals, transition metals, metalloids, halogens and noble gases. The periodic table can also tell you the number of electrons (4:05), valence electrons (6:30), protons (7:11) and neutrons (7:55).An experiment calls for the substance KBr, but you are out of it. Which of the following can you use instead? K2S, NaCl, MgBr2 (9:25)Thank you for listening to The APsolute RecAP: Chemistry Edition!(AP is a registered trademark of the College Board and is not affiliated with The APsolute RecAP.
