Volatile hydrides - Volatile hydrides

Japanese: 揮発性水素化物 - きはつせいすいそかぶつ

...When heated to high temperatures, hydrogen can combine with many elements to produce roughly three types of hydrides: (1) Volatile hydrides: These are hydrides of mainly nonmetallic elements, such as water _H2O , ammonia _NH3 , hydrogen sulfide _H2S , and hydrogen halides HX (X = F, Cl, Br, I), and are made up of molecules formed by covalent bonds, with low melting and boiling points. (2) Salt-type hydrides: These can be obtained by igniting alkali metals or alkaline earth metals with hydrogen. ...

From [Hydride]

...often exhibit strong reducing properties. (2) Volatile hydrides Also called gaseous hydrides, these include compounds with strongly electronegative elements on the right side of the periodic table, such as hydrogen fluoride (HF), hydrogen chloride (HCl), water ( _H2O ), hydrogen sulfide ( _H2S ), and ammonia (NH3 ₎ . Hydrogen atoms often have a positive partial charge (and sometimes a negative partial charge)....
