PPT-Intro to the Periodic Table & Atomic Structure

THINK ABOUT IT answer on your warmup 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. Michael Bailey & Marlena . Artis. Atomic Mass. Symbol. (Uranium). Atomic Number. The atomic number is the number of protons an atom has. The atomic mass is the atom’s mass often measured in AMUs (Atomic mass units) which weighs approximately 1/12 the mass of a carbon-12 atom. Patterns in Element Properties. Pure elements at room temperature and atmospheric pressure can be solids, liquids, or gases.. Some elements are colorless. Others. . are colored.. 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. 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. Elemental Properties and Patterns. The Periodic Law. Dimitri. Mendeleev (1869/1871) was the first scientist to publish an organized periodic table of the known elements.. He was taking a chemistry course in Russia and tried to find a way to organize the periodic table. . 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. 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. Rows and columns. 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: . Development of the Modern Periodic Table. 1. .. . A brief Intro to . Mendeleev’s . Periodic Table:. The Periodic . Law. 2. Modern . Periodic Table. 3. .. Classifying . Periodic Table:. Groups & Periods. Main Groups & Transition Metals. Atoms, Elements, & the Periodic Table Earth Science Intro Unit What is an Atom? Atom S mallest particle into which an element can be divided and still be the same element Building blocks of matter. Should create electron structures for given atoms.. Could work out . Ar. of given elements.. ------------------------------------------------. Starter: What is abundance?. Fill in the table. Subatomic. History. Organization. Introduction to . Bonding. Trends. Terms. The Periodic Law. States that the physical & chemical properties of the elements are periodic functions of their atomic numbers.. The Periodic Table. Section 6.1. .
