what is periodicity?

Dear Student
Periodicity is  the tendency to recur at regularintervals.

Periodicity is the essence behind the Periodic Table. As the name suggests, the Periodic Table is built up of repeating patterns that conform to certain rules.

For example elements

  •  Group I (the alkali metals) all have similar chemistry.
  • Atomic radii increases across Period 3.

This section of the course essentially looks at three aspects of periodicity.

1. Trends across Period 3

2. Trends in Group II (The Alkali-earth metals)

3. Trends in Group VII (the Halogens)

We hope that clarifies your query.
