Tetrahedral yog ib qho qauv molecular uas tshwm sim thaum muaj plaub daim ntawv cog lus thiab tsis muaj ib leeg nyob ib ncig ntawm lub hauv paus atom hauv cov molecule. Cov atoms khi rau lub hauv paus atom nyob ntawm cov ces kaum ntawm a tetrahedron nrog 109.5 ° kaum ntawm lawv. Ammonium ion (NH4+) thiab methane (CH4) muaj a tetrahedral molecular geometry.

Tib neeg kuj nug, dab tsi ua rau molecule tetrahedral?

Hauv ib tetrahedral molecule , muaj ib lub hauv paus atom sib txuas rau plaub lub atom nyob ib puag ncig, tsis muaj ib leeg electron khub. Cov ntawv cog lus tsim cov kaum ntawm 109.5 degrees. Qee qhov piv txwv ntawm tetrahedral molecules muaj xws li ammonium ion, methane ion thiab phosphate ion.

Vim li cas cov pa roj carbon muaj cov duab tetrahedral? Cov carbon muaj 4 valence electrons thiab yog li xav tau 4 ntau electrons los ntawm plaub hydrogen atoms kom tiav nws octet. Cov hydrogen atoms yog sib nrug deb li qhov ua tau ntawm 109o daim ntawv cog lus. Qhov no yog tetrahedral geometry . Qhov no molecule muab lub hauv paus rau lub tetrahedral geometry ntawm txhua qhov carbon nyob rau hauv ib tug hydrocarbon saw.

dab tsi molecules muaj tetrahedral zoo?

Tetrahedral Geometry Molecules ntawm methane , CH4 , ammonia , NH3 , thiab dej, H2O, txhua tus muaj plaub pawg hluav taws xob nyob ib ncig ntawm lawv lub hauv paus atom, yog li lawv txhua tus muaj cov duab tetrahedral thiab cov ces kaum ntawm 109.5 °.

Vim li cas alh4 tetrahedral?

Raws li cov ion muaj 2-them, muab ob qho O's ib qho hluav taws xob ib qho los ua rau lawv O¯ thiab tsim ib qho kev sib txuas ntawm lawv thiab S. Qhov ob O's ces muab ob npaug rau sulphur. Qhov no tsim 4 daim ntawv cog lus thiab tsis muaj ib leeg khub yog li cov ion yog tetrahedral ..
