For the first time, scientists have characterized a promethium coordination complex, advancing the understanding of ...

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 ...

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 ...

As the interactions between atoms are governed by the valence electrons, their findings shine light on the fundamental nature of chemical bonds, with implications for pharmacy and chemical ...

It is true that we know little in regard to what we symbolise by a shared pair of electrons, but even less was ever known of the inner meaning of the single bond of organic chemistry, although ...

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.

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the ...

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 ...

Boron, carbon, nitrogen and oxygen: these four elements can form chemical triple bonds with each other due to their similar electronic properties. Examples of this are the gas carbon monoxide ...

Yet because of their similar electronic properties, all four elements share a remarkable ability to form strong chemical ...

Researchers are opening up new horizons in chemistry: They present the world's first triple bond between the atoms boron and carbon. Boron, carbon, nitrogen and oxygen: these four elements can ...
