Each atom then has a complete outer shell of electrons. The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule contains ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...

The discovery of a stable single-electron covalent bond between two carbon atoms validates a century-old theory. Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, ...

A research group has successfully demonstrated that carbon-carbon (C-C) covalent bonds expand and contract flexibly in response to light and heat. This unexpected flexibility of C-C bonds could confer ...

Selective reaction of one alcohol among many in complex molecules can be achieved by the use of a catalyst that forms a single covalent bond to a nearby functional group. Fast, selective and high ...

The three states of matter can be represented by the particle model. This model explains the properties of substances in their different states, as well as changes of state. Changes of state: ...

Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries ...

This is a preview. Log in through your library . Abstract The generalized X-ray structure factor described in the preceding paper is used in an electron distribution study of the covalent bond in ...

The discovery of a stable single-electron covalent bond between two carbon atoms validates a century-old theory. The discovery of a stable single-electron covalent bond between two carbon atoms ...
