Purpose: Utilizing our comprehension of the arrangement of the elements in the periodic table (the way elements with common traits are grouped together), we will determine the name and location of each unknown element by clustering said elements with other known elements that they share the most characteristics with. In this lab we will momentarily fill the shoes of the Russian chemist Dmitri Mendeleev, who was the first to observe the patterns between elements arranged according to their properties. His periodic table left room for then undiscovered elements.
Analysis: Through examining the physical properties of common elements, inspecting the properties and trends in the elements on the periodic table, and identifying unknown elements based on observed trends we can form our own crude periodic table. None of the elements are radioactive. For unknown #5, noticing that the color is gold was all you’d need to know that the element was Au. It’s also a solid and soft, just like Cu and Ag, which are in the same group. Unknown #4 is a gas, so that automatically restricts it to either group 17 or group 18 (groups with nonmetal gasses). Just like all the other elements in group 18, though, the unknown element is colorless, barely conductive, and not soluble. After inserting Kr into the blank space in group 18, you would then be able to see that there is a pattern of increasingly higher melting points as you go down …show more content…
Unknown #2, or fluorine, cannot be placed anywhere on the periodic table except at the top of group 17 primarily because it is a gas. It would not fit into unknown #4’s place either because of
