Beginning students often do not see the difference between empirical and molecular formulas. Students think that polyatomic ions can easily dissociate into smaller ions. Students often fail to recognize the importance of the periodic table as a tool for organizing and remembering chemical facts. It is critical that students learn the names and formulas of common and polyatomic ions as soon as possible. They sometimes need to be told that this information will be used throughout their careers as chemists (even if that career is only one semester). Students often cannot relate the charges on common ions to their position on the periodic table.

Chemistry I Fill-in-the-blank Study Guide March 7, 2007 Page 2 Plato & Aristotle 384-322 B.C. The Atomic Theory Of Matter The Atomic Theory Of Matter Greek Philosophers 0. Plato & Aristotle said that there were no ultimately indivisible particles. 1. The atomic view of the matter faded for many centuries during which Aristotelian Philosophy dominated Western culture. Platos Periodic Table Platos Periodic Table Aristotle Added Properties The Atomic Theory Of Matter The Atomic Theory Of Matter 0. This went on for almost 2000 years because of the Catholic Church. 1. The Catholic Church agreed with the Aristotelian Theory. 2. To disagree with the church meant death. The Atomic Theory Of Matter The Atomic Theory Of Matter 3. Disagree with the church and you were burned at the stake. Burning At The Steak Burning At The Steak The Atomic Theory Of Matter The Atomic Theory Of Matter 0. Isaac Newton (16421727) favored the idea of aroms but he felt thinking of atoms in air is different from thinking of atoms as the fundamental building blocks of matter. 1. It was easy to visualize atoms as causing the things that are familiar with concerning air. You could easily imagine these little particles floating around and bumping into you and you would feel the wind, or up in the air causing clouds, but not so much as the building blocks of solids....
