Periodic tables is the plural of periodic table, the chart organizing chemical elements by atomic number and properties.
The standard periodic table arranges elements in rows (periods) and columns (groups) that reveal patterns in their behavior.
Scientists occasionally propose alternative periodic tables with different arrangements: Several periodic tables have been designed to emphasize electron configurations.
