- The Transition Metals So all the elements are arranged in columns according to how many valence electrons they have, and that tells you what they do in chemical reactions. Right--except it's not always quite that simple. So far I've been avoiding the elements in the middle of the periodic table, called the transition metals... Tell me about them. At first sight, they look like a confusing and ...www.colorado.edu/physics/2000/periodic_table/transition_elements.html
