1. The Periodic Table

2. Why is the Periodic Table important to me? You get to use it on the EOCT & Graduation tests. You get to use it on the EOCT & Graduation tests. It organizes lots of information about all the known elements. It organizes lots of information about all the known elements.

3. Pre-Periodic Table Chemistry … …was a mess!!! …was a mess!!! No organization of elements. No organization of elements. Imagine going to a grocery store with no organization!! Imagine going to a grocery store with no organization!! Difficult to find information. Difficult to find information. Chemistry didn’t make sense. Chemistry didn’t make sense.

5. Dmitri Mendeleev: Father of the Table HOW HIS WORKED… Put elements in rows by increasing atomic weight. Put elements in rows by increasing atomic weight. Put elements in columns by the way they reacted. Put elements in columns by the way they reacted. SOME PROBLEMS… He left blank spaces for what he said were undiscovered elements. (Turned out he was right!) He left blank spaces for what he said were undiscovered elements. (Turned out he was right!) He broke the pattern of increasing atomic weight to keep similar reacting elements together. He broke the pattern of increasing atomic weight to keep similar reacting elements together.

6. The Current Periodic Table Now the elements are put in rows by increasing ATOMIC NUMBER!! Now the elements are put in rows by increasing ATOMIC NUMBER!! The horizontal rows are called periods and are labeled from 1 to 7. The horizontal rows are called periods and are labeled from 1 to 7. Hint – You write a sentence from left to right on a line on a sheet of paper – you put a PERIOD at the end of the sentence. Hint – You write a sentence from left to right on a line on a sheet of paper – you put a PERIOD at the end of the sentence. The vertical columns are called groups are labeled from 1 to 18. The vertical columns are called groups are labeled from 1 to 18. Hint – Columns hold up the roof of a building so columns (groups) run up and down. Hint – Columns hold up the roof of a building so columns (groups) run up and down.

7. Groups…Here’s Where the Periodic Table Gets Useful!! Elements in the same group have similar chemical and physical properties!! Elements in the same group have similar chemical and physical properties!! (Mendeleev did that on purpose.) (Mendeleev did that on purpose.) Why?? They have the same number of valence electrons. Example: Aluminum 2 electrons are in the 1 st cloud 8 electrons are in the 2 nd cloud 3 electrons are in the third cloud (valence cloud for aluminum. They will form the same kinds of ions.

8. Families on the Periodic Table Columns are also grouped into families. Columns are also grouped into families. Families may be one column, or several columns put together. Families may be one column, or several columns put together. Families have names rather than numbers. (Just like your family has a common last name.) Families have names rather than numbers. (Just like your family has a common last name.)
