Metal - definition of metal by The Free Dictionary

But for chemists, a metal is a chemical element that loses electrons in a chemical reaction. Metal atoms do this because of the structure of their electron shells—the layers in which electrons are arranged around an atom''s nucleus. If an element''s outermost electron shell is filled, the element is stable and does not react easily.
