Front: Reading the Periodic Table. History of the Periodic Table:. At the conclusion of our time together, you should be able to:. . List one of the earliest contributors to the discovery of the elements. . Explain triads and who developed this table of the elements. 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. 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. 4. Interpreting the Periodic Table. Typically . they have a shiny . luster.. Relatively . high . density.. Malleable . ( they can be hammered into thin sheets. ).. Ductile . (they can be drawn into a wire. 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 .

Look at the periodic table you’ve been given, and highlight any patterns you see. . 2. Electron Configuration. An . “electron configuration”. of an atom is a particular distribution of electrons among available subshells. . The . notation for a configuration lists the . subshell . 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). What is the periodic table?. periodic- a regular repeating pattern. periodic table- arrangement of elements so that their physical and chemical properties follow a regular repeating pattern.
