The Periodic Table By PresenterMedia.comPresenterMedia.com

1. Attain a blank Periodic Table. 2. Elements are determined by the number of Protons; that is why they are organized by Atomic Number. 3. Atomic Number = Protons 4. Label each element with their Atomic Number. Write it on the top, left side of the square. Remember: You read the Periodic Table from left to right. Start with Hydrogen ( H) and stop at Barium (Ba) Periodic Table H 1

1. When you stopped at Ba, what did you notice? 2. Note 1: The arrows indicate where the Lanthanide and Actinide would fit into the Periodic Table. They are moved to the bottom of the table to save space. 3. Finish labeling the elements with their Atomic Number. Remember La – Lu are Atomic Numbers and Th- Lr are Periodic Table

Note 2: Something periodic occurs at regular or at least generally predictable intervals Periodic law - physical and chemical properties of the elements are periodic functions of their atomic numbers Periodic Table of Elements – a table of the elements, arranged by atomic number, that shows the patterns in their properties; based on the periodic law Periodic Table

There are 90 elements that occur naturally on earth There are 25 that are (3.) synthetic : made by scientist To represent synthetic elements, draw the following symbol on the bottom, right side of the element’s square. The synthetic elements are Tc (43) Rf – Uuq ( ) Pm (61) Np – Lr ( ) Periodic Table Rf

The Periodic Table is further divided into periods and groups/family. 5. Each horizontal row is called a period 6. Each vertical column is called a group/family Label the Columns. You start with 1 at Hydrogen and end at Helium with 18. Periodic Table

Label the Periods. This time you will go down the side of the Periodic Table. Hydrogen is 1, Francium is 7. Periodic Table

It is also divided into three major zones of elements. Zone 1: The Representative Elements are those elements within the first two families (Groups I and II on the far left) and the last six families or groups (on the right) of the Periodic Table. Zone 2: The Transition Metals are the elements in those Groups within the middle of the Table. Zone 3: The Inner Transition Metals Periodic Table

Using a red marker outline the representative elements. Using a blue marker outline the transition elements.

The periodic table, also depicts (shows) the state of matter that the element is at room temperature. Most of the pure elements are solid at room temperature. Only 11 naturally occurring elements are a gas. Only 2 elements (Br and Hg) are liquid at room temperature. To show that the elements are gas (look at your book’s periodic table), draw a balloon on the bottom right hand corner. To show that the elements are liquid draw a tear at the bottom right hand corner. Periodic Table H Br

The last step of creating your periodic table is to indicate whether the element is a metal, metalloid, or nonmetal. 7. Metals: 1. Except for Mercury they are all solids 2. have high melting points 3. Has luster (reflect light) 4. Good conductor of heat and electricity 5. Malleable (they can be pounded into sheets) 6. Ductile (they can be drawn out into wires) Periodic Table

8. Metalloid: Shares some properties with metals and some with nonmetals 9. Nonmetals: 1. are usually gases or brittle solids 2. Poor conductors of heat and electricity 3. include many elements that are essential for life Periodic Table

Using your book’s periodic table as a guide, correctly color the metals, metalloids, and nonmetals. - Metals - Metalloid - Nonmetal Periodic Table
