 * Common Misconceptions:**
 * The size of an atom would increase across a period because an additional electron is added.
 * Electronegativity and electron affinity mean the same thing.


 * Interesting Facts:**
 * It's thought that a metallic form of hydrogen exists in the high-pressure core of Jupiter.
 * Most of the elements on the periodic table are metals. The alkali metals, alkaline earths, basic metals, transition metals, lanthanides and actinides all are groups of metals.
 * There are 90 elements on the periodic table that occur in nature. All of the other elements are strictly man-made.


 * Resources:**
 * The Royal Society of Chemistry has heaps of student and teacher resources for many different topics. Here's a teacher resource for the Periodic Table.
 * A Periodic Table game that tests students knowledge of how well they can position elements, from the Association of the British Pharmaceutical Industry (ABPI).
