Question

Increasing order of ionic character of metal hydrides

Answer 1

Answer:

Explanation: 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.

Answer 2

Explanation:

it is the size of increasing order of ionic character of metal hybrids
