The variation of lattice energy with atomic number of the cation throughout these series is compared with the similar variation for the first transition series. It appears likely that the 5f shell, rather than the 6 d, is progressively filled in these actinide compounds. The lattice energy ...
Lattice Energy: The lattice energy of a compound is defined as the formation of gaseous ions from a solid ionic compound. It depends on the charge present on the ions and the size of the ions. Smaller the size and higher is the charge on ions, larger is the ...
In this paper we present an expression relating the lattice energy (U in kcal/mol) for the AIIIBV and AIIBVI semiconductors with the product of ionic charges (Z1Z2) and nearest-neighbor distance d (Å). The lattice energy of these compounds exhibit a linear relationship when plotted on...
hydrogen compounds/ A6150L Crystal bindingThe lattice energies of the high and low temperature forms of crystalline HCN have been calculated as a sum of long-range and short-range interactions. The former consist of electrostatic, inductive and dispersive terms whose values are calculated using a ...
The 496 is the first ionisation energy of sodium. Remember that first ionisation energies go from gaseous atoms to gaseous singly charged positive ions. The 122 is the atomisation enthalpy of chlorine. Again, we have to produce gaseous atoms so that we can use the next stage in the cycle. ...

Lattice energy refers to the sum of interactions between ions in a crystal structure, which is minimized by adjusting lattice parameters and atomic coordinates to achieve the lowest energy state. AI generated definition based on: Stratigraphy & Timescales, 2019 ...
In this paper, the effects of Nd 3+ ions substitution with Sm 3+ ions on the microwave dielectric properties of NdNbO 4 ceramics were investigated. X-ra... P Zhang,Y Zhao - 《Journal of Alloys & Compounds》 被引量: 5发表: 2016年 The relationship between bond ionicity, lattice energy,...
Organic heterostructure nanowires, such as multiblock, core/shell, branch-like and related compounds, have attracted chemists’ extensive attention because of their novel physicochemical properties. However, owing to the difficulty in solving the lattice mismatch of distinct molecules, the construction of ...
The linear muffin tin orbital method is applied to compute the energy properties of several ordered binary Fe-Ni, Fe-Co, and ternary Fe-Ni-Co compounds near the BCC-FCC transition, from first principles. The calculations use the local spin density and the Perdew-Wang gradient corrected ...
