No, lattice energy refers to the energy required to separate one mole of an ionic solid into its gaseous ions, while cohesive energy is the energy needed to break the forces between atoms or molecules within a substance to make them separate. So, they are not the same.

Explain why the theoretical lattice energies become less exothermic from AgF to AgI?
The decrease in exothermicity in theoretical lattice energies from AgF to AgI is mainly due to the decrease in the charge density of the anions as you move from fluoride to iodide. The larger iodide ions are less able to polarize in response to the cation, resulting in weaker electrostatic interactions and a less exothermic lattice energy.
Is the side centered cube a bravais lattice?
No, the side-centered cube is not a Bravais lattice. Bravais lattices are categorized based on their symmetry properties, and the side-centered cube does not meet the criteria for Bravais lattice classification.
How does lattice energy change with a change in the size of an ion?
Lattice energy increases as the size of an ion decreases. Smaller ions have higher charges density, leading to stronger electrostatic attractions between ions in the crystal lattice, resulting in higher lattice energy. Conversely, larger ions have weaker attractions, leading to lower lattice energy.

What is the use of reciprocal lattice in crystal?
The reciprocal lattice is a mathematical construct commonly used in crystallography to describe the periodicity of a crystal structure in reciprocal space. It provides a convenient way to interpret diffraction patterns obtained from a crystal, allowing researchers to determine the crystal structure, lattice parameters, and orientation of the crystal lattice. The reciprocal lattice is essential for analyzing diffraction data and understanding the relationship between crystal structure and diffraction patterns.
What is cohesive energy in case of NaCl?
If you think to lattice energy the value is 789 kJ/mol.

Born haber cycle n its applications?
it is used for calculating lattice energies of different ions.
What are the lattice energies of barium sulphate and calcium carbonate and how do they relate to dissolution in acids?
don't know xd
How lattice energy affect solubility?
A high hydration energy gives an increased solubility.
How would you compare the crystal lattice energy compared to the energies of the neutral atoms forming the ionic compound?
I don't know I have no arms :(
Is the side centered cube a bravais lattice?
No, the side-centered cube is not a Bravais lattice. Bravais lattices are categorized based on their symmetry properties, and the side-centered cube does not meet the criteria for Bravais lattice classification.
What is difference between crystal lattice and space lattice?
A crystal lattice refers to the arrangement of atoms or ions in a crystal structure, whereas a space lattice refers to the repeating 3D arrangement of points or nodes in space that represent the positions of lattice points in a crystal lattice. In other words, a crystal lattice describes the atomic arrangement within a crystal, while a space lattice defines the spatial arrangement of points representing the crystal lattice.
What is the attraction between substances of the same kind?
The attraction between substances of the same kind is called cohesive attraction or cohesive force. It is the property of similar molecules to stick together.
COHESIVE?
Forces of attraction btwn molecules of the same kind
What is the definition of cohesion force?
Cohesion force refers to the attractive forces between molecules of the same substance, causing them to stick together. These forces are responsible for phenomena like surface tension and capillary action. Cohesion is essential for the overall stability and properties of liquids.
Ionization energies of oxygen and xenon same or not?
No, the ionization energies of oxygen and xenon are not the same. Xenon has higher ionization energy compared to oxygen due to the increased number of electrons and stronger electron-electron repulsion in xenon.
