Chromium atoms muaj 24 electrons thiab lub plhaub qauv yog 2.8. 13.1. Cov hauv av xeev electron configuration ntawm hauv av xeev gaseous nruab nrab chromium yog [Ar]. 3d ib 5.

Ib yam li ntawd, tib neeg nug, pes tsawg 3d electrons yuav raug kwv yees hauv av hauv av rau chromium?

Tom qab 4s puv peb muab plaub seem electrons hauv 3d ib orbital thiab xaus nrog 3d4. Yog li qhov xav tau hluav taws xob configuration rau Chromium yuav 1s22s ib22 ib p63s ib23 ua p44s ib2 3d ib 9. Nco ntsoov tias thaum sau ntawv hluav taws xob configuration rau atom zoo li Cr , cov 3d ib feem ntau yog sau ua ntej 4s.

Qhov thib ob, kev teeb tsa hluav taws xob ntawm cr3+ yog dab tsi? Yuav ua li cas yog electron configuration ntawm Cr3 + 1s2 2s2 2[6 3s2 3p6 3d5 4s1 [Ar]3d5 4s1 [Ar]3d3.

Ib sab ntawm no, pes tsawg 3d electrons nyob hauv CR?

5 electrons

Vim li cas cov hluav taws xob configuration ntawm chromium?

Ib qho kev piav qhia rau Chromium , yog li ntawd, yog tias: Lub zog sib pauv maximized Πe stabilizes qhov no kev teeb tsa (3d54s1). Qhov maximization los ntawm yuav ua li cas muaj 5 unpaired electrons, es tsis txhob 4 (3d44s2).
