The periodic table is a fundamental part of understanding chemistry. Elements define our universe: they are the components and foundation of the substances that we interact with every day.

The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could ...

Is It Time to Upend the Periodic Table? 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.

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.

A new study lays the groundwork to expand the periodic table with a search for element 120, to be made by slamming electrically charged titanium atoms, or ions, into a californium target.

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.

In this periodic table of elements quiz, you have 10 minutes to name as many elements as you can, given only their symbol, atomic weight and the broad group they live in.

Scientists have started a new periodic table for quantum dots, which they refer to as “artificial atoms.” Quantum dots are nano-sized particles that are made of semiconducting materials ...
