Ntawm no, cov ntsiab lus twg yog kev zam rau Aufbau txoj cai?

Piv txwv li, ruthenium, rhodium, nyiaj thiab platinum yog tag nrho kev zam rau Aufbau txoj cai vim yog sau los yog ib nrab puv subshells.

Ib sab saum toj no, yog vim li cas electron configuration rau tooj liab 1s22s22p63s23p63d104s1 es tsis txhob 1s22s22p63s23p63d94s2? Ib tug puv sublevel yog ruaj khov dua li ib nrab-sau sublevel. Kev npaj ntawm electrons nrog tib spin yog me me li sai tau. Lub 4s orbital muaj zog ntau dua li 3d orbital.

Tsis tas li ntawd nug, koj sau li cas electron configuration rau D block ntsiab?

Feem ntau, cov electronic configuration ntawm cov no cov ntsiab lus yog (n-1) d 110ns 12. Tus (n–1) tseem nyob rau sab hauv d orbitals uas tej zaum yuav muaj ib txog rau kaum electrons thiab lub peripheral ns orbital tej zaum yuav muaj ib los yog ob tug electrons. Cov d – thaiv suav nrog thaj chaw nruab nrab flanked los ntawm s- thiab p- thaiv nyob rau hauv lub periodic rooj.

Vim li cas Cr thiab Cu qhia qhov tsis sib xws?

Tib yam tshwm sim nrog Cu . Peb ua tau pom tias hauv Cu d subshell muaj 9 electrons yog li kom ruaj khov nws xav tau 1 electron ntxiv hauv d subshell ces nws yuav siv 1 electron los ntawm s subshell thiab tam sim no Cu yuav ua kom ruaj khov hauv nws cov khoom siv hluav taws xob tshiab kev teeb tsa . Vim li no, Cr thiab Cu hu ua exceptional kev teeb tsa.
