HYDRIDES

binary hydrides are compounds formed by atoms of hydrogen and another element, and there are three types: metal hydride , hydracids Acids and Volatile Hydrides. How
made? Metal Hydride

To make metal hydrides is written first symbol of the metal, below the symbol of hydrogen (H) and then the valence of the metal. Formula: XHn

hydrohalic acids acids to make hydracids is written first symbol of Hydrogen (H) below the valence non-metal and past the command sulfur, selenium, tellurium, fluorine, chlorine, bromine or iodine. Formula: XnH
Hydrides VolatilesPara make volatile hydrides first write command nitorgeno, phosphorus, arsenic, antimony, boron, carbon or silicon, below the symbol of hydrogen (H) and then the non-metal valence correspondiente.Fórmula:

XHn How are they named? Metal Hydride

come from the combination of hydrogen and a metal. If the metal is combined with having a single valence are named by the words Hydride, and the name of the metal that is combined. In other nomenclatures Like the oxides, the only thing that instead of oxide hydride is placed.

Examples: Traditional / Stock / Systematics. ------------------------------------- CaH2
Hydride Calcium / Hydride Calcium / Calcium dihydride .
--------------------------------------- NaH Sodium Hydride / Sodium Hydride / Hybrid Sodium.

If the metal with which combined has two valences, it becomes like that of a valence metal but the name just a bear when she performs with lower valence and ico when acting with the valence greater and was removed prefix.

Examples: ------------------------------------- FeH3
ferric hydride. ------------------------------------- FeH2
Hydride ferrous.

hydrohalic acids are binary combinations between the hydrogen and the following non-metals:
Element Element


Valencia Valencia 2

Sulphur

1
Fluorine Chlorine Bromine


Selenium Tellurium Iodine

hydracids Acids are named only in the traditional nomenclature and systematics, and not in the Sock. Traditional

are named with the word acid followed by the name of nonmetal ending in water.
Examples: -------------------------------------
hydrochloric acid HCl. Hydrogen Sulfide H2S
-------------------------------------. Systematic

are named first putting the name of uro not finish metal. and continues with the words of hydrogen.
Examples: -------------------------------------
HCl hydrogen chloride. H2S
hidrógeno.Hidruros ------------------------------------- Volatile Sulfide
combinations are hydrogen with the following chemical elements, and contain the following valences:
