Mendeleev’s periodic table, published in 1869, was a vertical chart that organized 63 known elements by atomic weight. This arrangement placed elements with similar properties into horizontal rows.

The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius. Many scientists worked on the ...

The periodic table has become an icon of science. ... Mendeleev published a chart of the 60-odd elements known at the time, ... Based on Their Atomic Weight and Chemical Affinity. ...

The iconic chart of elements has served chemistry well for 150 years. ... Among its many achievements, the periodic table enabled chemistry to finally shed the taint of alchemy.

Created 150 years ago, the Periodic Table is a triumph of form and function. Now this design classic has been updated for the 21st century – and opened up to a new audience.

The periodic table of elements, devised by Russian chemist Dmitri Mendeleev, is a two-dimensional array of the chemical elements, ordered by atomic number and arranged 18 across by orbitals.

This is a big year for the Periodic Table of the Elements as the world celebrates the 150th anniversary of Dmitri Mendeleev's creation. We can now lays eyes on a fascinating relic of its history.
