Point out that the Periodic Table is also organized along a vertical and horizontal axis based on the properties of the elements. Hand out the periodic table information page for the students to read. Explain that Dimitri Mendeleev, a Russian chemist, was the first to publish the classification of the elements that gave us the format we use ...

The present organization of the elements is a product of the first periodic table published by Dmitri Mendeleev in 1869. The amazing accuracy of his predictions has been very important to chemists in this century. However, the basis of his arrangement was the atomic masses of the elements. This approach proved incorrect, as it would have placed ...

Use the periodic table to determine the electron configuration of the valence electrons for the following representative elements. (Recall, the principal quantum number is the same as the period number and the total number of valence electrons {s & p} is the same as the group number when using the older labeling). a. Ca b.
