Qhov sib txawv tseem ceeb ntawm lanthanide contraction thiab actinide contraction yog tias actinide contraction ntau dua lanthanide contraction.
Lo lus "kev cog lus" hauv lanthanide contraction thiab actinide contraction yog hais txog "qhov loj me me" nrog rau kev nce tus lej atomic. Yog li ntawd, lanthanide contraction yog qhov txo qis ntawm qhov loj ntawm ib qho atom ntawm lanthanide nrog rau qhov nce atomic tooj thaum actinide contraction yog hais txog tib yam tshwm sim nrog cov tshuaj hauv cov actinide series.
Lanthanide Contraction yog dab tsi?
Lanthanide contraction yog qhov txo qis ntawm qhov loj ntawm atoms nrog cov lej atomic ntau ntxiv hauv lanthanide series. Nws yog qhov txo qis hauv atomic radius thiab ionic vojvoog ntawm cov tshuaj lom neeg hauv lanthanide series. Tsis tas li ntawd, qhov no tshwm sim vim yog txhaws ntawm 4f orbitals nrog electrons ua ntej sau 5d orbital. Ntawm no, 4f electrons qhia txog kev tiv thaiv tsis zoo ntawm cov nqi hluav taws xob, uas ua rau 6s electrons txav mus rau lub nucleus ntawm lub atom, ua rau lub vojvoog me me.

Ntxiv mus, qhov kev sib cog lus no yog qhov tsis tu ncua. Cov lej atomic hauv lanthanide series suav nrog hauv qhov kev sib cog lus no yog los ntawm 57 txog 71. Lub caij muaj atomic tooj 71 yog Lutetium, uas muaj lub vojvoog ionic me dua li cov khoom siv tshuaj muaj atomic tooj 72 hauv cov khoom tom ntej.
Kev cog lus Actinide yog dab tsi?
Actinide contraction yog qhov txo qis ntawm cov atoms nrog cov lej atomic hauv cov actinide series. Qhov kev cog lus ntawm no yog qhov tshwm sim ntawm kev tiv thaiv tsis zoo ntawm ib qho 5f electron los ntawm lwm 5f electron ntawm tib lub orbital. Yog li, vim qhov kev tiv thaiv tsis zoo ntawm cov nqi hluav taws xob los ntawm 5f electrons, cov nqi hluav taws xob muaj txiaj ntsig zoo nce ntxiv, uas ua rau kev cog lus ntawm lub atom lossis txo qis hauv atomic loj.
Qhov txawv ntawm Lanthanide Contraction thiab Actinide Contraction yog dab tsi?
Lanthanide contraction yog qhov txo qis ntawm qhov loj ntawm atoms nrog cov lej atomic ntau ntxiv hauv lanthanide series thaum Actinide contraction yog qhov txo qis ntawm cov atoms nrog cov lej atomic hauv cov actinide series. Yog li, qhov sib txawv tseem ceeb ntawm lanthanide contraction thiab actinide contraction yog tias actinide contraction ntau dua lanthanide contraction.
Hauv qab no yog ib qho infographic uas muab cov ntsiab lus ntawm qhov sib txawv ntawm lanthanide contraction thiab actinide contraction.
Summary – Lanthanide Contraction vs Actinide Contraction
Yeej, lanthanide contraction thiab actinide contraction yog cov ntsiab lus tseem ceeb hais txog f thaiv cov ntsiab lus. Cov ntsiab lus no hais txog qhov txo qis ntawm atomic loj nrog nce atomic naj npawb. Qhov sib txawv tseem ceeb ntawm lanthanide contraction thiab actinide contraction yog tias actinide contraction ntau dua lanthanide contraction.
