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 ...

The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required ...

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 ...

Bonds are broken and made in reactions. Types of chemical reactions - OCR Gateway Oxidation is the gain of oxygen and reduction is the loss of oxygen. Neutralisation is the reaction between an ...
