"valence forces" is a correct and usable phrase in written English.
It is usually used in chemistry or physics when referring to the forces between atoms that attract or repel each other due to their charge. For example, "The valence forces between sodium and chlorine result in the formation of sodium chloride."
Thus, from a structural point of view, a molecule consists of an aggregation of atoms held together by valence forces.
In adhesive joints this contact is attained by intermolecular or valence forces exerted by molecules in the surface layers of the adhesive and adherend.
This indicates that the adsorption of Pb2+ onto NiO/CNT may be the chemisorption involving valence forces through the exchange or sharing of electrons between adsorbate and adsorbent [48].
This suggests that the adsorption may be the rate-limiting step involving valence forces through sharing or exchange of electrons between adsorbate and adsorbent (Taty-Costades et al. 2003; Ho and McKay 1999).
The pseudo-second-order rate expression is used to describe chemisorption involving valence forces through the sharing or exchange of electrons between the adsorbent and adsorbate as covalent forces, and ion exchange (Ho and Mckay 1998).
Therefore, the experimental results support the assumption behind the model that the rate-limiting step in the adsorption of dyes are chemisorptions involving valence forces through the exchange of electrons between adsorbent and dyes [7].
We have obtained the parameters of consistent valence force field (CVFF) for monoclinic hydroxyapatite.
The LJ parameters came from the consistent valence force-field (cvff 45, which is based on the experimental values and ab initio calculations.
This compound was chosen due to its expected high sodium diffusivity, predicted through high-throughput computations of sodium migration energies among 4314 compounds using the bond valence force field (BVFF) approach7 (Fig. 1(a)).
We have obtained the parameters for monoclinic hydroxyapatite in CVFF (consistent valence force field) from the known potential energy function of apatites.
The simulations were performed on crosslinked network of EPON-862 and curing agent-W (DETDA) using consistent valence force field (CVFF).
