Question

ionoic character of inoic hydride increase down the group 1. then why lattice energy decresase down the group 1.​

Answer 1

Answer:

As the size of the metal cation increases down the group, the lattice energy of the hydrides decreases down the group. ... Explanation: Since ionisation enthalpy of alkali metals decreases down the group, tendency to form cations as well as the ionic character of the hydrides increases.
