Introduction to The Periodic Table

The Periodic Table All elements in the periodic table are organized into groups based on similar chemical properties. Each square of the periodic table shows the symbol for the element, the atomic number and the atomic mass. Each element symbol will be a capital letter If the element symbol has two letters, only the first letter is capitalized

Organization of The Periodic Table Groups are vertical columns in the periodic table. Draw arrows and label them to indicate the direction of the groups on the periodic table

Organization of The Periodic Table Periods are horizontal rows in the periodic table. Draw arrows and label them to indicate the direction of periods on the periodic table

Organization of the Periodic Table The stair step line starting from Boron to astatine separates the metals from the non metals.

Organization of The Periodic Table Trace the stair step line in a very dark color Use arrows to represent the directions of the metals and nonmetals in reference to the stair step line. Metals← → Nonmetals

Organization of The Periodic Table Color all of your metals except for hydrogen a light blue Color all of your non metals yellow Color hydrogen pink

Organization of The Periodic Table Metalloids are all elements that touch the stair step line except for Boron and Astatine. There are seven metalloids:- Boron, Silicon, Geranium, Arsenic, Antimony, Tellurium, and Polonium Put a red circle around all metalloids

Organization of The Periodic Table Halogens are located in group 17 or 7/A, these elements are known as salt formers. F, Cl, Br, I, At Circle and label you halogen group.

Organization of The Periodic Table Noble gases are located in group 18 or 8/A. They are very stable, and do not react readily with other elements. All elements want to be like noble gases. Circle and label your noble gases

Lanthanides and Actinides The lanthanides series and the actinide series are placed below the periodic table They fit right after elements 57 and 89 They are placed below the table to keep the table from being too wide. Lanthanides → Actinides →

Types of Elements Shiny Good electrical conductor Good heat conductor Metals Nonmetals Mettaloids Halogen Noble Gases Shiny Good electrical conductor Good heat conductor Solid at room temperature Mallible Ductile Gases at room temperature Brittle Poor conductor of heat Poor conductor of electricity Has properties of both metals and nonmetals Semi conductors of electricity Can be solid, liquid, or gas at room temperature Form diatomic molecules High electronegativities Salt formers Generally unreactive (because of their stable outer shell)
