THMG143 – Periodic Table Part 1


Mike and Bob attempt to break down the periodic table that adorns seemingly every Haz Mat Schools walls, but no one knows really what those things mean. We take a trip into a foundational knowledge that will leave you on the street with real world smarts.

  1. Periodic Table
  2. A little philosophy
    1. Why do we want to know this?
      1. Crazy thing that confuses everybody
      2. From the Haz Mat Tech to the layperson, it screams NERD!
    2. What do we NEED to know about this chart?
      1. It looks like a box with letters and numbers arranged in some sort of pattern that you are not quite grabbing as of yet.
      2. They seem to form a rectangle, but one of a shape that you are not confident of.
        1. 18 across, and 7 deep
        2. But there’s gaps
          1. Mostly along the top
      3. And now you start hearing people talk about the chart as if it means something, like they know what it means. It’s A translator of some sort, a soothsayer to the events coming.
        1. But you…nothing….
    3. In order to fully grasp what we are discussing, check the website at www.thehazmatguys.com for this episode. We’ll have the chart we are referring to in the notes
      1. This table is cool because it is layered, meaning that if you open it in Adobe reader, you can turn off or on the layers you want to see, or print this in High Res.
        1. Thank you to Ptable.com
  3. History
    1. Let’s go back to the beginning of the chart to clown named Mendeleev.
      1. He created this in 1869
        1. This is when Jesse James robbed a bank that made him famous
        2. And Ulysses Grant was elected the 18th president of the United states
    2. But it actually has its roots even before that
      1. In 1789 Antoine Lavoisier came up with a loose grouping of elements 
      2. In 1829 a dude named Johann Wolfgang Dobereiner started to group them by chemical properties
        1. this was refined by Leopold Gmelin in 1843
        2. and further by August Kekule in 1857 and by many others that brought us to the final version that we use today by Mendeleev
  4. General Info
    1. 118 Elements
      1. We can quickly identify an element by either its letter abbreviation or its atomic number.
      2. And every so often they discover a new element
        1. In December 2015 they discovered nihonium (Nh), Moscovium (Mc), Tennissine (Ts) and oganesson (Og)
        2. once they are discovered, they are submitted and approved by IUPAC (International Union of Pure and applied Chemistry)
      3. The first 94 elements are naturally occurring
        1. And nothing after Einsteinium (99) have ever been found past microscopic amounts of around 300,000 atoms
