A classroom chart bearing an early version of the periodic table of elements has been discovered in a University of St. Andrews chemistry lab. Dating back to the 1880s, the chart is thought to be ...

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.

The iconic chart of elements has served chemistry well for 150 years. But it’s not the only option out there, and scientists are pushing its limits.

Unless you were really into chemistry, you probably found the table frustrating. The Beacon calls its table the Periodic Table of Tech , and I, for one, would have found it much more interesting ...

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.

As of 2019, the Periodic Table of the Elements has been around for 150 years. Maybe you've felt a certain chemistry with 2019 but don't know why? Maybe it's because this year marks the 150th ...

Today, the periodic table is organized by atomic number, which is the number of protons in the nucleus. But they didn’t know about protons then, so they organized everything by atomic weight.

Elements heavier than uranium don’t exist naturally on Earth. Researchers make these massive elements at the end of the periodic table by smashing existing atoms together in particle accelerators.

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.

An international team of scientists has shed light on the extreme ends of neutron and proton numbers. Their goal is to investigate the limits of the periodic table of chemical elements. How far ...

Who created the periodic table? Dmitri Mendeleev, a Russian chemist and inventor, is considered the "father" of the periodic table, according to the Royal Society of Chemistry.In the 1860s ...
