Sentences with phrase «bond between atoms»

Elementary chemistry distinguishes two kinds of strong bonds between atoms in molecules: the covalent bond, where bonding arises from valence electron pairs shared between neighboring atoms, and the ionic bond, where transfer of electrons from one atom to another leads to Coulombic attraction between the resulting ions.

Because chemical reactions occur so rapidly, chemists can only infer how chemicals change during the process, as bonds between atoms break and reform, branches rotate or join to form rings, and three - dimensional structures shift.

In parallel work, Mikhail Eremets of the Max Planck Institute for Chemistry in Germany found a novel bond between atoms of nitrogen, the most common element in Earth's atmosphere.

Physicists have long known that chemical bonds between atoms are flexible — like springs connecting spheres.

«Each resonator behaves as an atom, and the connections between them behave as bonds between atoms,» said Kitt Peterson, the lead author and an electrical engineering graduate student.

But, just a few months ago, my lab mate told a group of us that he was not invested in teaching his female summer student about how bonds between atoms exist in physical space.

[1] Organic molecules without multiple bonds between atoms are collectively called saturated molecules.

A more orderly environment seems to limit the ability of molecules to change their shape, or conformation, by rotating around single bonds between atoms.

In 2009, Gross and colleagues imaged the individual bonds between the atoms of a molecule for the first time.

«We've had a strong belief in graphene, because it is a very robust, ultrathin, material and forms very strong covalent bonding between its atoms in the horizontal direction,» Kim says.

Using a state - of - the - art atomic force microscope, the scientists have taken the first atom - by - atom pictures, including images of the chemical bonds between atoms, clearly depicting how a molecule's structure changed during a reaction.

The bonds between the atoms break down and decay.

Because the carbon atoms in a C36 fullerene must strain to form a sphere, the bonds between atoms are brittle; thus, the molecule is very reactive and quickly decomposes in air.

Basic chemistry tells us that a bond between atoms can form if it is energetically more favorable for the atoms to stick together than staying apart.

Relying on a technique called infrared spectroscopy to explore the bonds between atoms, the researchers noticed it attaching to positive hydrogen atoms.

This bond is much weaker than the bond between atoms in a crystal.

Probing the way electrons form and break bonds between atoms is critical to tracing the workings of chemistry at the ground level.

The scientists began by building a database of 1,500 odor - producing molecules, cataloging 1,664 different traits — their size, the strength of the chemical bonds between their atoms, and so on.

When any material is bent, the bonds between atoms are stretched or compressed to accommodate the bending, but in nanoscale materials there is time for the atoms to also move, or diffuse, from the compressed area to the stretched area in the material.

It's going to destabilise a lot of bonds between atoms.
