WitrynaCovalent hydrides. Metallic hydrides. Ionic or Saline hydrides. In this hydride type, hydrogen molecules bond with the s-block elements, which are highly electropositive. They are also known as alkali metals or alkaline earth metals. In this reaction, hydrogen reacts at a high temperature. Examples include NaH, CaH2, and KH. Properties of … Witryna4 kwi 2024 · The hydride is not ionic because of the lower electronegativity difference in comparison with the other s-block elements. Also, Be is small with relatively high charge and the H − ion is a large anion, due to these differences in the sizes, Be ends up having a covalent bond with hydrogen.
Witryna12 kwi 2024 · But it we are asked to compare the ionic character of hydrides (LiH, NaH, KH, RbH, CsH), we can not use the Fajan's rule. This is because, here the anion is very small ( H X −) as compared to the cations (alkali metal cations). The ionic character is this case can thus be compared on the basis of Lattice energy.
