THINK ABOUT IT – answer on your warm-up sheet or scratch paper. W. hat are the 3 main groups on the periodic table?. What are the 3 main parts of an atom?. You need to get . 3. different . color pencils. Section 1. . - Organizing the Elements. Section 2. . - Exploring the Periodic Table. Section 3. . - Families of Elements. State Standards. CLE 3202.1.3 . Characterize and classify elements based on their atomic structure. Trends and Similarities. Trends of the Periodic Table:. At the conclusion of our time together, you should be able to:. . Give a trend across and down the Periodic Table for metallic characteristics, reactivity, atomic radius and ion radius, . Classification of . elements: . The arrangement of elements in such a manner that elements with similar properties are grouped together while elements with dissimilar properties are separated. .. The classifications are as follows. Russian chemist. 1869 – discovered a pattern to the elements. Grouped the elements according to their similar properties and eventually arranged them in order by atomic mass.. THIS CREATED THE PERIODIC TABLE OF THE ELEMENTS. By 1869, there were 63 known elements. Mendeleev organized elements by atomic mass and chemical reactivity. Created the first widely accepted periodic table. Mendeleev Continued. Mendeleev found patterns by arranging cards with names, masses, and other physical and chemical properties of elements. Turn to page 3 in the Unit Note Packet . History of the Periodic Table. In the . mid-1800’s. , . Dimitri Mendeleev published a table of all of the known elements, 70 elements to be exact. . Not until . Periodic table. Elements are arranged based on similarities in their properties. Dmitri Mendeleev is credited with our current periodic table. Even predicted the existence of elements that were not yet discovered(i.e. Gallium). Law. Geneva High School. Section 5-1 History of the Periodic Table.  By 1860, more than 60 elements had been discovered, yet chemists had no way of organizing them or agreeing on basic properties of the element.. Section 1. Development of the Modern Periodic Table. The periodic table evolved over time as scientists discovered more useful ways to compare and organize the elements.. Section 1: .
