The redox reactions affect the number of covalent bonds that a carbon makes to a heteroatom substituent, such as nitrogen and oxygen. Each redox state of carbon (Fig. 2) is associated with a class ...

This, of course, poses quite a conundrum, as many believe single-electron chemical bonds can’t exist. That’s because all of the current known covalent bonds—where atoms connect by sharing ...

Here, we report on an allotropic form of nitrogen where all atoms are connected with single covalent bonds, similar to carbon atoms in diamond. The compound was synthesized directly from molecular ...

Small molecules - AQA A covalent bond is a shared pair of electrons. Covalent bonding forms molecules. Substances with small molecules have low melting and boiling points, and do not conduct ...

On the other are so-called main group elements like carbon and nitrogen, which prefer sharing electrons in covalent bonds. Carbon and nitrogen in particular can share up to three of their outer ...

Gilliard Jr. of the University of Virginia and David Wilson of La Trobe University has created the first known compound to contain a multiple bond between an s-block metal and nitrogen (Angew.

But nitrogen gas -- which consists of two nitrogen atoms held together by a strong, triple covalent bond -- doesn't break apart under normal conditions, presenting a challenge to scientists who ...

Save guides, add subjects and pick up where you left off with your BBC account. The slideshow shows a covalent bond being formed between a hydrogen atom and a chlorine atom, to form hydrogen chloride.
