transition metal

One of a series of chemical elements that have properties that exhibit a change from more metallic properties (metals) to less metallic properties (nonmetals) as one moves from left to right in the periodic table of elements. For example, many of the elements between calcium and arsenic display this phenomenon, e.g., titanium, chromium, and manganese.
