Sentences with phrase «by electrons shared»

Materials are held together by electrons shared between atoms.

Not exact matches

The atomic size and structure of nitrogen make it an excellent choice for this purpose because it can fit naturally into a strong network of carbon atoms by creating bonds (sp2) in which electrons are shared by the whole network.
Most significant was the September unveiling by Japanese researchers of a powerful linkage between two silicon atoms that share three pairs of electrons — a so - called triple bond.
A chemical bond is the physical phenomenon of chemical substances being held together by attraction of atoms to each other through sharing, as well as exchanging, of electrons - or electrostatic forces.
For the last 100 years, they have done that mostly by making and breaking the strong covalent bonds that form when atoms share electrons.
Atoms of most elements, such as hydrogen, oxygen and carbon, form tight chemical bonds by sharing electrons with their neighbours in order to give each atom a stable configuration of electrons.

Unlike regular polymers like the polystyrene that vending machines cups are made from, or the clear polycarbonate that CDs are pressed with, the molecules in the new rubbery polymers are not linked by strong covalent bonds — which involve atoms sharing electrons.
In addition to differences in brightness, Gross and colleagues found that bonds that are more electron - dense actually appear shorter than bonds that share fewer electrons — though only by a few picometres, or 10 - 12 of a metre.

A supramolecular assembly — a supermolecule — is an explicitly designed complex of molecules held together by noncovalent bonds — bonds that do not involve sharing electrons.
This was 5 years (to the month) after the precursor to the AFM, the scanning tunnelling microscope (STM), had first been successfully tested at IBM's Zurich Research Laboratory by Binnig and the late Heinrich Rohrer, and 7 months before Binnig and Rohrer were awarded a share of the Nobel Prize in Physics for the design of the STM (the prize was shared with Ernst Ruska, the inventor of the electron microscope).
Normally, molecules are joined by strong covalent bonds in which the atoms share electrons, but in the chain they were instead linked by a freer mechanical bond.
