In these semiconductors, that polarity can flip under an electric field—and stay that way even after the field is gone.

Chemical bonding refers to the attraction between atoms and can come in several different types with varying strength. It allows the formation of substances with more than one atomic component and ...

Everything in the world is made from about 100 different chemical elements that join together in different ways to form all the solids, liquids and gases we see around us. All of the elements have ...

According to PAP, citing information from the scientific journal Nature, a covalent bond that requires only a single electron is the first new chemical bond to be discovered in over ten years.

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 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 ...

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 ...
