periodic table of elements

Chemistry's organizational grid

The periodic table of elements is a chart organizing all known chemical elements by atomic number and electron configuration, arranged so that elements with similar properties fall into columns.

It's a fundamental reference in chemistry, predicting how elements behave and combine.

Often shortened to periodic table: Every chemistry classroom has a periodic table on the wall.
