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 ...

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 ...

Students look more deeply into the structure of the atom and play a game to better understand the relationship between protons, neutrons, electrons, and energy levels in atoms and their location in ...

This means that the chemical formula used for a metal is simply the symbol for the element. For example, the formula for iron is Fe, even though a piece of iron contains very many iron atoms.

The hydrogen bond plays a critical role in diverse biological phenomena. Although discovered 90 years ago, the precise chemical nature of this unique interaction has remained in dispute.

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 ...

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 ...

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