The periodic table organizes elements according to similar properties — so anyone can tell the characteristics of an element simply by looking at its location on the table.

The periodic table's organization provides important information about an element's structure and properties. Read on to learn more about how the periodic table was made over 150 years ago and why ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

The periodic table currently has 118 chemical elements (SN: 11/30/16). The five heaviest elements were all produced using a beam of calcium-48. That’s a variety, or isotope, of calcium with 28 ...

The periodic table as we know it is widely credited to Dmitri Mendeleev, a Russian chemist who kept reference cards on the elements and their atomic weight. In 1869, he noticed that the elements ...

Elements in the periodic table are arranged in order of increasing atomic number. The atomic number represents the number of protons in an atom's nucleus, uniquely identifying each element.

The first was Technetium, but we’ve now synthesized 24 “artificial elements” - filling in Mendelev’s gaps, and also extending the periodic table all the way 118, Oganesson, with its half ...
