The inner shells of an atomâs electrons are full and stable. For the most part, they contribute little to the way the atom reacts. The largest factor in how an atom reacts is the makeup of its outer shell electrons. The periodic table naturally groups together elements with similar outer shells (Transition metals, halogens, etc.).
This lesson will answer those questions. The elements in the periodic table are arranged in rows according to atomic number and in columns according to the configuration of the outer orbit or shell. The chart below just shows the first 18 elements, so you can get an idea of how the periodic table arranges them.
