Tsis tas li ntawd, vim li cas hydrogen tsis yog ib feem ntawm alkali hlau?
Hydrogen yog tsis yog ib alkali hlau nws tus kheej, tab sis muaj qee yam khoom zoo sib xws vim nws qhov yooj yim ib qho proton (nyob hauv lub nucleus), ib qho kev npaj electron. Ib leeg electron muaj nyob rau hauv ib tug s-orbital nyob ib ncig ntawm lub nucleus.
Tom qab, lo lus nug yog, dab tsi pab pawg neeg yog hydrogen ib feem ntawm? Hydrogen yog ib qho tshwj xeeb heev ntawm lub sij hawm lub rooj thiab tsis yog ib tsev neeg. Thaum hydrogen zaum hauv Pab pawg Kuv, nws tsis yog alkali hlau.
Kuj paub yog, vim li cas hydrogen nyob rau hauv pab pawg 1 yog tias nws tsis yog hlau?
Tsis zoo li cov pab pawg ib yam hydrogen yog kom meej meej tsis yog hlau (nws yog ib qho roj ntawm chav tsev kub) thiab yog ib tug tsis zoo conductor ntawm tshav kub thiab hluav taws xob. Nws tsis yooj yim tsim H + cations thiab tsim covalent bonds nyob rau hauv feem ntau cov tebchaw, whereas pab 1 metal yooj yim tsim cations thiab tsim tsuas yog ionic bonds.
Puas yog hydrogen suav nrog hauv Pawg 1?
Pawg 1 : Hydrogen thiab Alkali Metals. Alkali hlau yog cov tshuaj muaj nyob hauv Pawg 1 ntawm daim ntawv periodic. Txawm tias feem ntau teev nyob rau hauv pab pawg 1 vim nws txoj kev teeb tsa hluav taws xob, hydrogen tsis yog technically ib qho alkali hlau vim nws tsis tshua muaj tus cwj pwm zoo sib xws.

Muaj ob txoj hauv kev los saib cov ntaub ntawv hais txog cov pab pawg no. Qhov sib txawv ntawm pab pawg qhia tias ob lossis ntau pawg sib txawv li cas, qhov sib txawv hauv pab pawg qhia qhov sib txawv ntawm cov kev kawm uas nyob hauv tib pab pawg. Nyob rau hauv-pab pawg sib txawv tuaj yeem tshwm sim thaum saib ntawm kev tshawb fawb ntawm pab pawg
Vim li cas lub cube cag ntawm tus lej tsis zoo yog tus lej tsis zoo?
Tus lej tsis zoo lub voos xwmfab hauv paus yuav tsis zoo Txij li qhov ntsuas tus lej txhais tau tias tsa nws mus rau lub zog thib 3 - uas yog khib - lub voos xwmfab ntawm cov lej tsis zoo yuav tsum yog qhov tsis zoo. Thaum lub qhov hluav taws xob tawm (xiav), qhov tshwm sim tsis zoo. Thaum lub qhov hluav taws xob qhib (daj), qhov tshwm sim yog qhov zoo
