Hydrideionen
Hydrideionen is the chemical species with the formula H-. It is an anion where a hydrogen atom has gained an electron, giving it a negative charge. This makes it a hydride, specifically a hydride ion. In contrast, a neutral hydrogen atom has one proton and one electron. A hydrogen molecule (H2) consists of two hydrogen atoms bonded together.
The hydride ion is a powerful reducing agent. Its small size and high charge density make it
Hydride ions are also important in organic chemistry, where they are transferred by reagents like lithium aluminum
