The lab purpose was to identify nine of the unknown elements from Mendeleev's lab from 1869. Identify the components of the elements, study its physical properties, observe the properties and trends in the elements on the periodic table draw conclusions and identify unknown elements based on observed trend in properties.

Mendeleev is a was a Russian Chemist who formed the periodic law and formed his own version of the periodic table of elements. Who was very accurate with his predictions of the Periodic table which is why most chemists went along with his prophecy.

The objective of this purpose was to put us in Mendeleev's shoes, as in trying to reconstruct the periodic table. For instance there are a couple unknown elements and those are

    Atomic Mass Of Beanium Lab

    In this Beanium lab, the objective was to make sense of the numbers used to calculate average atomic mass. By separating, counting, and weighing beans we were able to create the numbers used to calculate the weight of one bean. From there, we could use the total number of beans to produce the percent abundance for each type of bean. These were the numbers that we had to produce in order to understand how and why there are many types of isotopes for each element. In doing this lab, we can think through the importance of finding the average atomic mass and not just using a single isotope for an element.…

    Disappearing Spoon: Dimitri Mendeleev, Robert Bunsen, And Fritz Haber

    After college Mendeleev went to the great Robert Bunsen who supervised him, later on Mendeleev went back to St. Petersburg. At St. Petersburg he became a professor and gained interest in elements. A scientist by the name of John Newlands made his version of the Periodic Table which he presented to the science society. Then Mendeleev made his version in the table but not the perfected one. Mendeleev understood that many each element has different characteristics, which some scientist had a problem with at this period in time.…

    Materials. Numerous substances in the experiment were used. The most frequently used was the unknown due to the need to test its physical and chemical qualities. When a solution of the unknown was made, 1.000 g of the unknown and 1.0 mL of water was used to make it. To test for the possible ions, 1.0 mL of silver nitrate and 1.0 mL of nitric acid were used for the ion test.…

    Dmitri Mendeleev's Lab

    The purpose of Mendeleev’s lab is to observe the physical characteristics and properties of common elements. In addition, observe arrangements and trends on the periodic table. Finally, the main goal is to draw conclusions and identify the locations of unknown elements based on given trends and properties. Through observing characteristics and trends, one is introduced to reading the periodic table and its elements, based on how it is arranged. Dmitri Mendeleev was a Russian scientist who is credited with creating the first periodic table.…

    Initially they started by studying emissions from various minerals which led them to win a Nobel Prize in 1903 that they shared and another one to Marie alone in 1911. "Their first accomplishment was to show that radioactivity was a property of atoms themselves." For scientists it was the most important of Curies discoveries, because it helped other scientists to understand the atomic structure of matter. "The second, more famous discovery, was the discovery of polonium and radium. " The most radioactive element they experimented with was radium, a substance that does not exists free in nature.…

    Dmitri Mendeleev: The Periodic Table Of Elements

    The periodic table of elements contains about 118 elements, and there are also many trends in the periodic table, such as ionization energy, electronegativity, and many other trends. When Dmitri Mendeleev created the periodic table, not all of the elements were present. It took many other scientists to discover the other elements. Mendeleev started to notice the patterns in the properties and atomic weights of halogens, alkali metals, and alkaline metals. He created a card for each of the 63 known elements at that time that contained its element symbol, atomic weight and its characteristic chemical and physical properties ("Periodic Table,").…

    The periodic table is a very familiar site for many people, and almost all of us have spent a lot of time staring at it in Chemistry classes during our time in high school or college. The periodic table is an extremely important tool and is a great way to help students visualize a large volume of information about the elements and their relationship with each other. During your time learning about the periodic table you likely didn’t spend a lot of time looking at the elements with an atomic number of 90 or higher. Likewise, depending on how up-to-date your table was, there were probably more than a few elements that had not been numbered or were undiscovered altogether, but this has changed.…

    Unknown Salt Lab Report

    During the entire lab, the main purpose was to, Identify the given unknown salt through a variety of experiments which yielded valuable quantitative and qualitative data. Before any experiments were carried out, multiple properties were compiled in order to have a source to compare the found results with. Beginning with the first experiment to determine if the unknown salt was hygroscopic, efflorescent, deliquescent or none of the above properties. This test was done through weighing an amount of the salt and reweighing after 15 minutes which would show if the salt had one of the above properties (either by gaining mass from the air, losing mass to the air, turning to solution) or none of the properties. Furthermore, tests were done to identify…

    The Basis Of Mendeleev's Periodic Table

    The basis of Mendeleev’s periodic table was categorizing the elements according to their physical and chemical characteristics with regard to their atomic weights. Mendeleev was the first to come up with a structure for the periodic table with columns and rows. There were other scientists who have worked on tabulating information of the elements even before Mendeleev, however, he was the first scientist to come up with a periodic trend to predict the properties of elements which were not discovered at that time. Therefore, Mendeleev’s periodic table had empty spaces/gaps, so that these elements, once found can be then included. Gallium and Germanium were two such elements.…
