Orientational order describes the relational and clustered order
shared between atoms and groups of atoms over distances.
Materials are held together by electrons
shared between atoms.
Not exact matches
This organic whole that began from an initial high bang and eventuated into the present universe is distinguished by a form of unity and diversity radical beyond all imagining: infinite differences, and diversity that is marked not by isolation but by
shared atoms over millennia as well as minute - by - minute exchanges of oxygen and carbon dioxide
between plants and animal.
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.
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.
Of the two types of
atom, oxygen has more pull on the electrons that they
share to form the bonds
between them, so the oxygen becomes slightly negatively charged and the hydrogens slightly positive.
The most detailed images yet made of the chemical bonds in a molecule show what large - scale models had long assumed: the more electrons that two
atoms share, the shorter the bond
between them.
But these structures are unstable because electrostatic forces are weak compared with the covalent bonds formed
between atoms that
share electrons.
The single -
atom moving finger of the nc - AFM could feel not only the individual
atoms but the forces representing the bonds formed by the electrons
shared between them.
It's called non-molecular ice, because the water molecule is broken apart and the hydrogen
atoms are
shared between neighboring oxygens.
Molecules like HBr and HCl which have a permanent dipole, resulting from an unequal
sharing of the bonding electrons, have a dipole which oscillates as the bond distance
between the
atoms oscillate.
