Periodic Table

The majority of the elements in the periodic table are

• Non-metals

• Metals

• Metalloids

The transition elements are located

• On the left side of the periodic table

• On the right side of the periodic table

• In central section of the periodic table

Elements that have properties of both metals and nonmetals:

• Inert gases

• Metalloids

• Transition metals

The stair‐step line running diagonally from aluminum to polonium divides the

• Lanthanides and actinides
