PPT-Atoms and the Periodic Table

Atoms and the Periodic Table Atomic Structure ATOM the smallest particle that has the properties of an element From the early Greek concept of the atom to the modern atomic theory scientists have built on and modified existing models of the atom. How do solar systems form?. B. Stellar Nurseries . C. A. How did the solar system form?. Astro. Comics Presents…. Long ago…. Nebula. Hmm…I am just moving around randomly.. Before Planets. A nebula is a cloud of dust and gas in space.. 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..

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 . 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. 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.. Mr. . Polard. Physical Science. Section 1 . Structure of Matter. Vocabulary – Section 1.
