With the United Nations declaring 2019 “the International Year of the Periodic Table,” this lighthearted look at the periodic table from chemist and high school science teacher James is perfect for ...

Electronegativity, an essential characteristic of all elements in the periodic table, measures an atom's ability to attract electrons towards itself within a chemical bond. This vital theoretical ...

The periodic table isn’t just a list of elements—it’s a map of predictable patterns called periodic trends. These trends, like atomic radius, electronegativity, and ionization energy, help scientists ...

The periodic table has become an icon of science. Its rows and columns provide a tidy way of showcasing the elements — the ingredients that make up the universe. It seems obvious today, but it wasn’t ...

The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...

One hundred fifty years after Russian chemist Dmitri Mendeleev published his system for neatly arranging the elements, the periodic table it gave birth to hangs in every chemistry classroom in the ...

This year marks the 150th anniversary of the publication of Mendeleev’s Periodic Table of Chemical Elements in 1869. In celebration, the United Nations Educational, Scientific, and Cultural ...

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 ...

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. By Siobhan Roberts When Sir Martyn Poliakoff, a ...

In a significant breakthrough for the scientific community, a new element has been confirmed on the periodic table. This discovery holds potential implications for a wide range of scientific fields, ...
