The Periodic Table and the Elements : 

The Periodic Table and the Elements What is the periodic table ? What information is obtained from the table ? How can elemental properties be predicted base on the PT ?

Dmitri Mendeleev (1869) : 

Dmitri Mendeleev (1869) In 1869 Mendeleev and Lothar Meyer (Germany) published nearly identical classification schemes for elements known to date. The periodic table is base on the similarity of properties and reactivities exhibited by certain elements. Later, Henri Moseley ( England,1887-1915) established that each elements has a unique atomic number, which is how the current periodic table is organized.

Slide 5: 

Every table has:

Periodic Table: Metallic arrangement : 

Periodic Table: Metallic arrangement Layout of the Periodic Table: Metals vs. nonmetals Metals Nonmetals

Periodic Table: The three broad ClassesMain, Transition, Rare Earth : 

Periodic Table: The three broad ClassesMain, Transition, Rare Earth Main (Representative), Transition metals, lanthanides and actinides (rare earth)

Across the Periodic Table : 

Across the Periodic Table Periods: Are arranged horizontally across the periodic table (rows 1-7) These elements have the same number of valence shells. 2nd Period 6th Period

Infamous Families of the Periodic Table : 

Infamous Families of the Periodic Table Notable families of the Periodic Table and some important members:

2. Trend in Atomic Radius : 

2. Trend in Atomic Radius Atomic Radius: The size of at atomic specie as determine by the boundaries of the valence e-. Largest atomic species are those found in the SW corner since these atoms have the largest n, but the smallest Zeff.

3. Trend in Ionization Potential : 

3. Trend in Ionization Potential Ionization potential: The energy required to remove the valence electron from an atomic specie. Largest toward NE corner of PT since these atoms hold on to their valence e- the tightest.

4. Trend in Electron Affinity : 

4. Trend in Electron Affinity Electron Affinity: The energy release when an electron is added to an atom. Most favorable toward NE corner of PT since these atoms have a great affinity for e-.
