Periodic Table Review Activity. Definition. What does PERIODIC mean? A repeating pattern Mendeleev left some spaces in his table because not all elements lined up according to atomic mass. He used info he knew about surrounding elements to PREDICT properties and masses of unknown elements.
How about that!

The physical and chemical properties of the elements are periodic functions of their atomic number.
The tendency of atoms to gain or lose electrons so they acquire 8 electrons in their outer energy level for stability
attraction of an atom for an added electron; to form an anion
estimate of the size of an atom a cation
distance between the nucleus and the likely location of electron cloud
ability of an atom to compete with other atoms for electrons shared between them
