Final answer:
Elements in groups 3-12 of the periodic table are classified as transition metals, which are shiny, malleable metals that conduct heat and electricity well.
Step-by-step explanation:
An element found in groups 3-12 of the periodic table is classified as a transition metal. These are elements that have partially filled d orbitals and are characterized by their ability to form multiple oxidation states and complex ions. All of the transition elements are metals, and they are known for being good conductors of heat and electricity, as well as being shiny and malleable.
The element found in group 3-12 of the periodic table is classified as a transition metal.
Transition metals are a group of elements that are located in the middle of the periodic table, between the main-group elements. All transition metals are metals. They have unique properties, such as being good conductors of heat and electricity and having high melting points. Some examples of transition metals include iron, copper, and silver.
