Theli-hydride Ke metsoako ea lik'hemik'hale e kopanyang liathomo tsa haedrojene molek'huleng ea tsona.
Ho amoheloa mekhahlelo e meraro ea li-hydride:
- Metallic tšepe: Ke tsona tse entsoeng ka likarolo tsa alkaline le alkaline-earth, ke hore, le tse ling ka ho le letšehali la tafole ea nakoana ea likarolo. Ke metsoako e sa fetoheng e bonts'ang conductivity. Hydrogen e fumanoa ho bona joalo ka hydride ion H¯. Ka har'a sehlopha sena ho a khonahala ho khetholla li-hydride tse thehang lisebelisoa tsa motlakase (ho tloha sehlopheng sa 1 le sa 2); li-hydride tsena hangata li bitsoa saline hydrides. Li-hydride tsa letsoai ka kakaretso li tiile kapa tse bohlooho tse tiileng tse fumanoang ka tšebetso e tobileng ea tšepe e nang le hydrogen maemong a phahameng.
- Li-hydride tse sa sebetseng kapa tse se nang tšepe:ke tse entsoeng ka likarolo tse seng tsa tšepe empa li na le motlakase o monyane haholo, ka nitrogen, phosphorus, arsenic, antimony, bismuth, boron, carbon le silicon: tsena tsohle li amohela mabitso a ikhethileng, ka nqane ho lebitso le akaretsang; kaofela ke li-metalloid kapa tšepe tse tsoang ho p block. Li ka bitsoa li-hydride tsa limolek'hule kapa tsa covalent, hobane li na le litlamo tse kopaneng. Li theha liminerale tsa likarolo tse ikhethang. Silane, hydride sehlopheng sena, e na le thahasello e ntseng e eketseha bakeng sa boleng ba eona ha ho etsoa li-nanoparticles.
- Li-hydride tsa haedrojene:(eo hape e bitsoang hydracids feela) e tsamaellana le motsoako oa haedrojene le halogen (fluorine, chlorine, bromine kapa iodine) kapa le antigenic element (oksijene, sebabole, selenium, tellurium); ke feela maemong a ho qetela moo haedrojene e sebetsang ka nomoro ea eona e ntle ea khase (+ 1) 'me karolo e' ngoe ke eona e sebetsang ka nomoro e fosahetseng ea khase (-1 ho halogen, -2 ka amphogens).
Mehlala ea li-hydride

Tšebeliso ea li-hydride
Har'a ts'ebeliso ea li-hydride re ka bolela tsa Li-desiccants le li-reducer, tse ling li sebelisoa e le mehloli e hloekileng ea haedrojene.
Calcium hydride e bohlokoa haholo joalo ka moemeli oa ho qhibiliha oa manyolo. Sodium hydride e hloka tlhokomelo e kholo ha e sebetsoa, kaha e sebetsa ka matla ka metsi mme e ka hotetsa.
Haeba mollo o hlaha ka lebaka la ho hotetsa ha hydride ena, se ke oa sebelisa metsi ho e tima, hobane e tla e ne e tla hlahisa malakabe a mangata. Mollo ona oa tima Litima-mollo tsa phofo.
