검증된 단계별 안내1
Identify the position of copper (Cu) on the periodic table. Copper is located in the d-block, specifically in group 11 and period 4.
Recall the classification of elements based on their groups: Alkali metals are in group 1, noble gases are in group 18, and halogens are in group 17.
Understand that transition metals are elements found in the d-block, which includes groups 3 through 12.
Since copper is in group 11, which is within the d-block, it is classified as a transition metal.
Therefore, based on its position in the periodic table, copper (Cu) is classified as a transition metal.
