Gregory Bosch Jr. September 5, 2006 Chemistry Notes: Naming Chemical Compounds In order to assign names, we should refer to the periodic table so that these compounds somewhat resemble the names of the elements they represent. Periodic Table: Mendelehev sought to arrange the elements based on their atomic weights. However, he noticed many different things and now the periodic table is arranged based on the number of protons within the element. On the table, the atomic number is above the name of the element except of to the bottom left. All Nonmetals, including normal gases, are on the right side of the periodic table. Those that are solids are not exact metals and are “somewhat pastey.” Column one on the table are the alkali metals. Column two contains Alkaline earth metals. The transition metals are the group numbers 2 – 11 and rows 4 to 7. They are in the middle of the table. Most of the Periodic table is occupied by metals.
