What is the concept of periodicity?

In the context of chemistry and the periodic table, periodicity refers to trends or recurring variations in element properties with increasing atomic number. Periodicity is caused by regular and predictable variations in element atomic structure.

What does periodicity depend on?

The periodic properties of an element depend on valency and number of shells in an atom. As we move down a group the number of shell increases successively such that the number of the shell of an element is equal to the number of periods to which it belongs.

What are the three categories of periodicity?

This is what is meant by periodicity or periodic table trends. There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals.

What factors affect periodic trends?

There are three factors that help in the prediction of the trends in the periodic table: number of protons in the nucleus, number of energy levels, and the shielding effect. The atomic radii increase from top to the bottom in any group. The atomic radii decrease from left to right across a period.
