Final answer:
The transition metals are located in the d block of the periodic table, which is found between Groups 3-12 and includes elements with partially filled d orbitals.
Step-by-step explanation:
The transition metals are located in the d block of the periodic table. These elements, which have partially filled d orbitals, are found between Groups 3-12. The d block is characterized as the middle 10 columns of the periodic table. While the s block consists of the first two columns on the left side of the periodic table, and the p block refers to the right-most six columns, the d block is distinct in that it includes the transition metals known for their unique chemical and physical properties such as conductivity and malleability. The f block, often considered separate, is comprised of the lanthanides and actinides and does not include the transition metals.
