Atoms and the Periodic Table

Dalton put it to paper ... the atomic theory that is ... and chemistry has not been same sense. We now spend meaningful amounts of time explaining behavior based on what we think those little darlings (atoms that is) are doing. The idea that these very little indestructible (well on normal everyday energies) atoms just rearrange is what chemists use as the basis of explaining the behavior of all matter. This LM gets right down to the it (matter that is) ... The basis of matter (Solids, liquids, and gases) is called the atom. A large enough chunk of like atoms is called the element. Elements are grouped in a periodic way (repeating chemical properties in the same column) by their physical and chemical properties. The periodic table organization is so well done that having a periodic table in your hands is like being given answers to exam questions. Too many parenthetic parts here. Better read it again.

Lets learn more about the tool called the periodic table ...

Orientation

Atoms are to elements as molecules are to compounds. One you can see and one you cannot. One has a specific mass while to other is calculated from an average. The periodic table is put together from observable data and represents the elements not atoms. The atoms which make up the elements can be a bit different from each other. Time to get started! Elements and Isotopes Video - excellent introductionhere.

Discovery and/or Exploration (10 Points)

ON CAMPUS Class: Arrive to lecture with your POGIL workbook. We will work on these in class.

ONLINE Class: You are to work on the following in your workbook, post three aspects of each not already posted as group work in the wiki area, and discuss ideas using the comments section while making any corrections to the wiki. You will have a separate wiki page for each ChemActivity. If the heading already exists, someone in your group already created it and it is time for you to edit the page and add your content. Make sure the wok stays in the same order as in the workbook.
