in the periodic table below, shade the f - block elements.

Brief Explanations:

The f - block elements are the lanthanides (from Ce - Lu) and actinides (from Th - Lr). They are characterized by the filling of f - orbitals. On the periodic table, they are usually shown as two separate rows at the bottom to make the table more compact.

Answer:

Shade the elements Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb), Lutetium (Lu) in the first of the two bottom - rows and Thorium (Th), Protactinium (Pa), Uranium (U), Neptunium (Np), Plutonium (Pu), Americium (Am), Curium (Cm), Berkelium (Bk), Californium (Cf), Einsteinium (Es), Fermium (Fm), Mendelevium (Md), Nobelium (No), Lawrencium (Lr) in the second of the two bottom - rows.
