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. What makes up matter?. By Amelia. Atoms. : an atom is the smallest particle of an element. Atomic number. : the number of protons in a nucleus is the elements atomic number. Each element is made of one kind of atom, so elements are called pure substances . and Periodicity. Chemistry. Outline. PowerPoint Presentation by Mr. John Bergmann. The Elements. . elements known to the ancients… . Element names come from a variety of sources. . place names… . 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.

Despite the differences between elements, groups of elements share certain properties.. 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. 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). 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.. 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.. EQ. : Just WHERE are these elements with . similar . properties?. Wake Up!. Sing along (if you’d like!). Song: Day 3 with the words. Song: Day 2 with pictures. Song: Day 1 on the periodic table. 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: .
