2. Fe is a transition metal in period 4, group 8 of the periodic table, in the d-block.

3. Ag is a transition metal in period 5, group 11 of the periodic table, in the d-block.

4. U is an inner transition metal in period 7, group 3 of the periodic table, in the f-block.

5. O is a main group element in period 2, group 16 of the periodic table, in the p-block.
