You will get to learn about the history of the Periodic Table and how the elements are arranged. Learn to easily locate metals, nonmetals and metalloids on the table and learn how atomic mass is calculated.
After completing this tutorial, you will be able to complete the following:
Which element type constitutes most of the Periodic Table, and where are these elements located on the Periodic Table?
~ Most of the elements in the Periodic Table are metals. Metals are located in the left side and middle of the Periodic Table.
Which element is in the upper left of the Periodic Table?
~ Hydrogen is a nonmetal and is located in the upper left of the Periodic Table.
Where do the elements at the bottom of the Periodic Table fit into the overall table? Why are they at the bottom?
~ There are two rows of elements located at the bottom of the Periodic Table. The top row contains lanthanides and the bottom actinides. These elements are actually placed after the second elements in the sixth and seventh periods. However, the table would be too long if the elements were inserted there. This configuration is also preferred by scientists because it makes for a more organized table.
