What Is Periodic Variation

Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii

What is the meaning of periodic variation?

A periodic trend is a regular variation the properties of an element with increasing atomic number. A periodic trend is attributed to regular variations in the atomic structure of each element.

How does periodic variation occur?

The elements in groups (vertical columns) of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells. … These properties vary periodically as the electronic structure of the elements changes.
