Modern periodic table
Understand the Problem
The question is asking for information about the modern periodic table, which is a tabular arrangement of the chemical elements organized by their atomic number, electron configurations, and recurring properties. The user is likely looking for a description, its significance, or examples of elements within it.
Answer
The periodic table organizes elements by increasing atomic number, with seven periods and 18 groups.

Answer for screen readers
The periodic table organizes elements by increasing atomic number, with seven periods and 18 groups.
More Information
The modern periodic table, based on Mendeleev's initial work, is a critical tool in chemistry that allows scientists to understand element properties and predict chemical behavior by looking at their positions.
Tips
Sometimes confusion arises between the periodic table's arrangement by atomic number versus atomic mass as was done in early versions. Always remember it's based on atomic number in the modern version.
