what is Hydride?

Answer 1

chemical formual is H-
and it is a bleach

Answer 2

A hydride is a compound of hydrogen with more electropositive elements.

Originally, the term hydride was reserved strictly for compounds containing hydride ions, usually in combination with metals, but the definition has been broadened to compounds (usually simple binary) involving hydrogen in direct bond with another element.

Hydrides can be roughly classified into three main types by the nature of bonding and structure:

- Ionic hydrides
- Covalent hydrides
- Transitional metal hydrides, interstitial hydrides.

In main group element hydrides electronegativity of an element respective to hydrogen determines the compound to be either of the first two types. An electropositive metal, from the left side of the Periodic table, forms ionic hydrides whereas an electronegative element (usually from the table's right side) forms covalent hydrides; however silane is one of the exceptions.

Answer 3

Hydrogen also forms ionic bonds with some metals, creating a compound called a hydride. Two atoms form an ionic bond when one atom donates an electron to the other atom. The resulting difference in electric charge between the two atoms makes them attract each other and bond together. In the ionic bonds of hydrides, the metal atom gives hydrogen an electron, making hydrogen a negatively charged ion (H-) and the metal a positively charged ion, for example a sodium ion (Na+). The two oppositely charged ions then attract each other and bond to form a salt, such as sodium hydride (NaH).

Answer 4

It is the isolated atomic hydrogen anion, H?. It consists of a singly charged positive nucleus and two electrons. The electron-electron repulsion almost overwhelms the nuclear-electron attraction. Thus, the “extra” electron is held weakly and is readily donated. Ionic salts containing this large and easily polarized ion are highly reactive, strongly basic, and powerfully reducing. This makes them important reagents despite the fact that they are readily destroyed by the presence of the relatively acidic compound water (H2O) or by exposure to the relatively oxidizing dioxygen (O2) as found in air. See also Electron configuration.

The term hydride also refers to salts containing the H? anion and a highly electropositive alkali or alkaline-earth metal as the cation. The salt names reflect this high ionic character, for example, sodium hydride (NaH). In such salts the ionic radius of H? is comparable to that of Cl?.

Answer 5

Anything with an "ide" on the end is an anion, meaning a negative charge. Hydrogen is either -1 or +1. Since the ending is "ide", hydride is H^-1.

Answer 6

It's H- --a hydrogen that has two electrons. Hydrogen is weird because it's the only element with fewer electrons than helium. That means it can reach a stable noble gas configuration by losing an electron (giving it no electrons), OR by gaining an electron, giving it the same configuration as helium. Hydrogen, therefore, can become a positive or negative ion. Heavier atoms need eight valence electrons to be stable, and they can't be close enough to eight to form stable anions AND close enough to zero to form stable cations.

(Helium is also stable with two electrons, but since neutral helium already has two electrons, it doesn't tend to ionize like hydrogen does.)
