Which Of The Carbonyl Compounds Are Susceptible To The Type Of Reactivity That NaH Provides? The ions are atoms that have gained one or more electrons (known as anions, which are negatively charged) and atoms that have lost one or more electrons (known as cations, which are positively charged). Four main bonding types are discussed here: ionic, covalent, metallic, and molecular. Explanation: A covalent hydride is a hydride in which the elements of compound form a bond by sharing of electrons. Water and other protic solvents cannot serve as a medium for ionic hydrides because the hydride ion is a stronger base than hydroxide and most hydroxyl anions. It is an ionic material that is insoluble in organic solvents (although soluble in molten Na), consistent with the fact that H − ions do not exist in solution.
