Atomic Structure and the Periodic Table

In this section, we look at the structure of atoms and the periodic table. We start by looking at a key experiment which led to the development of the current, nuclear model of atomic structure. We then look at how to use the atomic number and the mass number to work out the structure of atoms of specific elements. Next we look at how Dmitri Mendeleev developed the modern periodic table and then explore different groups in the periodic table.
