Is aluminum, Al, a representative or transition element?
Answer (2)
Aluminum (Al) is located in the p-block of the periodic table.
Representative elements are in the s-block and p-block.
Transition elements are in the d-block.
Therefore, Aluminum is a re p rese n t a t i v e element.
Explanation
Problem Analysis The question asks us to identify whether Aluminum (Al) is a representative or transition element based on its position in the periodic table.
Locating Aluminum on the Periodic Table Aluminum (Al) is located in the p-block of the periodic table. Representative elements are those found in the s-block and p-block. Transition elements are those found in the d-block.
Classification Since Aluminum is in the p-block, it is a representative element.
Examples
Understanding the classification of elements as representative or transition elements is crucial in chemistry. For example, in material science, knowing whether an element is a transition metal helps predict its ability to form alloys and its catalytic properties. Representative elements like aluminum are commonly used in structural materials due to their lightweight and corrosion resistance. This classification aids in selecting appropriate elements for specific applications based on their chemical behavior.
Aluminum (Al) is classified as a representative element because it is located in the p-block of the periodic table. In contrast, transition elements are found in the d-block. Thus, Aluminum is a representative element.
