From the burning of wood to the action of medicines, the properties and behavior of matter are governed by the way chemical elements bond with one another. For many of the 118 known elements, the ...

To expand the periodic table, it might be time to go titanium. A new study lays the groundwork to expand the periodic table with a search for element 120, to be made by slamming electrically charged ...

An international collaboration led by a research group from GSI/FAIR in Darmstadt, Germany, has achieved the first ...

Chemists have measured for the first time the bond dissociation energy of a superheavy element compound, confirming that ...

The first measurement of a chemical bond in a superheavy element compound shows that relativistic effects weaken the seaborgium-carbonyl bond, inverting the trend seen in lighter homologs.

This lesson utilizes an adaptation of the board game Periodic: A Game of the Elements to help students better understand both general periodic trends and the law of conservation of energy. This ...
