-A repeating pattern of properties. Might I suggest that you watch this: http://www.schooltube.com/video/03d81990... A BBC documentary called 'Chemistry: A Volatile History". It's the second episode dealing with the periodic table, it's really quite good. If this helped can i please have a medal? :)
