Step-by-step solution
Ionic hydrides are compounds form between hydrogen and the most active metals, especially with the alkali and alkaline-earth metals of group one and two elements. Covalent hydrides are formed when hydrogen reacts group 13 to group 17 elements. All the group 13 elements form electron deficient compounds with hydrogen. All group 14 elements form electron precise compounds. Elements from groups 15 through 17 form such bonds that have excess electrons which are present as lone pairs. (a) MgH 2 is an ionic compound. (b)
