Question

"The lattice energies of alkaline earth metal salts are much higher than these of alkali metal salts."
Answer whether the above statement is true or false.
If true enter 1, else enter 0.

Answer 1

The salt with the smaller cation has the higher lattice energy. Alkaline earth metals are smaller in size than respective earth metals of their period and therefore, have higher lattice energies. Higher lattice energies cause the alkaline earth metals to be more reactive than the alkali metals toward group 15 elements.
