Transition elements are known for many properties, except for having a low melting point, which is not typical of this group. They exhibit characteristics such as catalysis, color formation, complex ion formation, and variable oxidation states. Therefore, the correct answer is the low melting point. ;
Transition metals are known for their high melting points, catalytic properties, and ability to form colored compounds and complex ions. They are characterized by multiple oxidation states, which allow them to participate in a variety of chemical reactions. As such, a low melting point is not a property of transition metals.
