The Periodic Table

The Periodic Table By PresenterMedia.com

Periodic Table • Attain a blank Periodic Table. • Elements are determined by the number of Protons; that is why they are organized by Atomic Number. • Atomic Number = Protons • 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) 1 H

Periodic Table • When you stopped at Ba, what did you notice? • 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. • Finish labeling the elements with their Atomic Number. Remember La – Lu are Atomic Numbers 57- 71 and Th- Lr are 89-103.

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 ( 104 -114 ) • Pm (61) • Np – Lr ( 93 -103 ) Rf

Periodic Table • 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.

Periodic Table • 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. Br H

Periodic Table • 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
