9.33 What do you expect the nature of hydrides is, if formed by elements of atomic numbers 15, 19, 23 and 44 with dihydrogen? Compare their behaviour towards water
Answer-
Atomic Number 15 19 23 and 44 are phosphorus, potassium, vanadium, and ruthenium respectively.
hydrides of these elements are
(i)- its an electron rich species also a covalent molecule.
a lone pair of electron.
(ii)Hydrides of potassium- dihydrogen forms an ionic hydride. It is crystalline and non-volatile in nature
(iii) hydrides of vanadium and ruthenium- Both elements belong to d- block. They form metallic and non-stoichiometric hydrides. They are metallic in nature.
