The energy required to completely separate one mole of a solid ionic compound into its gaseous ions is referred to as lattice energy. Higher values indicate that the lattice is highly stable and will require a lot of energy to break down. How do you find the lattice energy trend? By compar...
Now, we are going to present you with factors that have a certain influence on lattice energy. Lattice Energy and Factors Two factors can have an impact on the lattice energy trend. Ionic Radius is a measurement of ion`s size. Lattice energy is higher in the compounds that consist of smal...
Specify which compound in the pair of the ionic compounds has the higher lattice energy. Mg_2N_2 or NaCl = NaCl The following compounds all display the NaCl structure (i.e. they are isomorphous). For the pair below, indicate which would ...
In the cycles this time, we are interested in working out what the enthalpy change of formation would be for the imaginary compounds MgCl and MgCl3. That means that we will have to use theoretical values of their lattice enthalpies. We can't use experimental ones, because these compounds obv...

Look carefully at the reason for this. The lattice enthalpy is the highest for all these possible compounds, but it isn't high enough to make up for the very large third ionisation energy of magnesium. Why is the third ionisation energy so big? The first two electrons to be removed from...

Many covalent compounds have some degree of charge separation, i.e. they are polar, due to bond polarization. What happens to group 2 carbonates when heated? CaCO3(s)——>CaO(s) + CO2(g) What does thermal decomposition of group 2 carbonates depend on? the further down the group, the ...
First, we are aware that the bipolar effect can produce an increasing trend in thermal conductivities at high temperatures. However, the increase in GeTe appears to be much steeper compared to PbSe and PbTe32,34,35 (Fig. 3). Moreover, the presence of Ge vacancies should make the sample p...
