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).

4p electron thiab 4s electrons thiab daim ntawv Ga3 +
Muaj pes tsawg tus electrons nyob hauv nruab nrab atom ntawm AR 40?
Muaj 18 protons los ntawm argon element.Muaj 18 electrons vim nws nruab nrab, thiab 22neutrons vim 40 - 18 = 22
Muaj pes tsawg neutrons nyob rau hauv chromium atom nrog ib tug loj tus naj npawb ntawm 54?
Chromium 54: Tus lej atomic Z = 24, muaj 24 protons thiab 24 electrons. Tus lej A = 54. Tus lej ntawm neutrons = A – Z = 54 – 24 = 30
Muaj pes tsawg protons nyob rau hauv nruab nrab chromium atom?
Yog li ntawd muaj 24 protons nyob rau hauv lub nucleus ntawm ib tug chromium atom. Tus naj npawb ntawm cov electrons nyob rau hauv ib lub atom yog sib npaug rau tus naj npawb ntawm protons li atoms yog hluav taws xob nruab nrab. Ib qho atom ntawm chromium muaj 24 electrons. Qhov hnyav atomic ntawm chromium yog kwv yees li ntawm 52
Muaj pes tsawg electrons nyob rau hauv lub zog thib ob ntawm ib atom ntawm txhua lub caij?
Thaum thawj theem zog muaj 2 electrons, tom ntej no electrons mus rau theem ob lub zog mus txog rau theem thib ob muaj 8 electrons. Thaum lub zog thib ob muaj 8 electrons, tom ntej no electrons mus rau qib peb lub zog mus txog rau theem peb muaj 8 electrons
