The Periodic Table

Today we had a follow up on a previous ed-chat about the periodic table. This was Mr.Roehl's sub, Mr. Delwhich's, first ed-chat that he taught in. I thought that it was very good because it covered the basics and I feel that I learned something useful. He helped us learn that a element consists of an atomic number, atomic symbol, and the atomic weight (average atomic mass). The atomic number tells us how many protons (positive charge) are in the element and how many electrons (negative charge) there are. The atomic symbol has a particular letter[s] for the element. The atomic number shows how many neutrons there are, and the atomic mass unit (AMU). Some of the atomic symbols have nothing to do with the name of the element because the elements are older and found in nature so they were originally named in Latin. We also learned that vertical rows on the periodic table are called families because they show similar characteristics. Today in the follow up we played a fun game of jeopardy where my team was Nate, Redmon, and me. We won and the game was fun and I feel I gained new knowledge of the periodic table of scientific elements.
