Which has higher lattice energy NaCl or CsCl?
CsCl has more ionic bonds than NaCl. The lattice energy is directly proportional to the ion charge and inversely proportional to the radius of the atom. The radius of Cs+ is now much greater than Na+ between NaCl and CsCl, even though CsCl is more ionic, but there is still more radius and thus less lattice energy.
Which has higher lattice energy LiCl or CsCl?
Thus we can conclude that LiCl has highest lattice enthalpy.
Which shows the highest lattice energy CsCl?
So, NaCl has more lattice energy than CsCl. Was this answer helpful?
What is the lattice energy of CsCl?
Consider CsCl, which has a primitive cubic lattice with one ion occupying the corners of the cube and the other ion located in the center of the cube. The lattice parameter is a = 412.3 pm, the Madelung constant is 1.763, and the compressibility is 5.55×10–11 m2/N.
Which has the highest lattice energy?
1 Answer. Ernest Z. (1) MgO has the highest lattice energy.
Which has highest lattice energy?
Which has maximum lattice energy?
The lattice energy is inversely proportional to the size of cation and anion. Among the given compounds, the size of cation and anion is smallest for LiF. Hence, it has maximum lattice energy.
What is the lattice energy of calcium fluoride?
The value of lattice energy of MgF2, CaF2 and ZrO2 molecules are, -2913 Kj/mole , -2609 Kj/mole and- 8714.5 kJ/ mole respectively. In case of molecule, the extent of charge on both ‘Mg’ and’ Ca’ metal is, +2 and the extent of charge on ‘F atom is, -1 . That is, both cations and anions contain same extent of charge.
How do you find the lattice energy trend?
Lattice Energy Trends To summarize, lattice energy increases as we increase ion charge and decrease the distance. More specifically, it increases from left to right across periods and from bottom to top up groups.
How do you find the highest lattice energy?
The smallest ions will be able to get closest to each other. They will have the smallest distance between centres and will have the largest lattice energies. The smallest ions are at the top of the Periodic Table. Mg2+ is smaller than Ca2+ , so MgO has the largest lattice energy.
What increases lattice energy?
As we increase the ion charge variable, lattice energy increases. This means that ions with larger charge values will produce ionic compounds with greater lattice energies. In turn, ions possessing weaker charges decrease the lattice energies of their compounds.
