Answer:

Modern Periodic Table

• It considers atomic number of elements as the most fundamental property of elements.

• The modern periodic table clarifies why elements in a group show similar properties but elements in different groups show different properties.

• The modern periodic table explains why periodicity in properties of elements exists.

• The modern periodic table tells us why the properties of elements are repeated after 2, 8,18 and 32 elements.

ADVANTAGES OF THE PERIODIC TABLE:

• It is easier to remember the properties of an element if its position in the periodic table is known.

• The periodic table has made the study of chemistry systematic and easy. It acts as an aid to memory.

• The type of compounds formed by an element can be predicted by knowing it position in the periodic table.
