From nearly indestructible metals, like tungsten, to delicate clouds in the sky, atoms make up everything around us. But do ...

Calcium becomes a +2 ion and each chlorine becomes a -1 ion. The +2 calcium ion and the two -1 chloride ions attract each other and form an ionic bond and the compound calcium chloride. One calcium ...

Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, have earned the nickname of forever chemicals from their ...

leading to clues about Promethium’s chemical bonds. Understanding Promethium and its bonding properties will help ORNL ...

Ken Wade recalls his own undistinguished part in the space race, and notes how carboranes revitalized boron hydride chemistry and modified our ideas of chemical bonding. In the 1950s, during the ...

Ionic compounds close ionic compoundAn ionic compound occurs when a negative ion (an atom that has gained an electron) joins with a positive ion (an atom that has lost an electron). form a regular ...

The opposite is true if we want to make new bonds. Energy is released when new chemical bonds are formed, so bond making is an exothermic process. Breaking or making the same chemical bond will ...

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 ...

An international group of scientists, including chemists from Utah State University, report helium can bond with sodium at high pressure. Here, an 8c-2e bond is found inside every empty Na8 cube ...
