Refer to the explanation below.

Ca is a main group element in period 4, group 2 of the periodic table, in the s-block.
Fe is a transition metal in period 4, group 8 of the periodic table, in the d-block.
Ag is a transition metal in period 5, group 11 of the periodic table, in the d-block.
U is an inner transition metal in period 7, group 3 of the periodic table, in the f-block.
O is a main group element in period 2, group 16 of the periodic table, in the p-block.
Pb is a main group element in period 6, 14 of the periodic table. It is a post-transition metal and is in the p-block of elements.
