27 electrons

Hais txog qhov no, pes tsawg valence electrons nyob hauv cobalt?

9 valence electrons

Kuj Paub, muaj pes tsawg lub orbitals nyob hauv cobalt? Cobalt yog ib qho kev hloov pauv hlau nyob rau lub sijhawm thib plaub uas maj mam sau nws lub plhaub thib peb nrog cov khoom siv hluav taws xob. Cobalt muaj kaum tsib electrons nyob rau hauv nws lub plhaub thib peb uas tuav lub siab tshaj plaws ntawm kaum yim electrons (raws li pom nyob rau hauv zinc).

Yog li ntawd, cobalt puas muaj 9 valence electrons?

Nov yog cobalt electron configuration: [Ar] 3d7 4s2. Muaj 2 's'-type electrons ntawm cobalt cov sab nraud, los yog valence , cev. Tab sis vim cobalt cov ib qho kev hloov hlau, lub 7 'd'-type electrons suav tau li valence electrons , txawm tias lawv tsis tshua muaj kev cuam tshuam nrog ib yam dab tsi. Muaj 2 lub 9 valence electrons , nyob ntawm cov ntsiab lus.

Dab tsi yog tus naj npawb ntawm protons neutrons thiab electrons hauv cobalt?

Daim duab ntawm lub nuclear muaj pes tsawg leeg thiab electron configuration ntawm ib tug atom ntawm cobalt-59 (atomic tooj: 27), feem ntau isotope ntawm lub caij no. Lub nucleus muaj 27 protons (liab) thiab 32 neutron (xiav). 27 electrons (ntsuab) khi rau lub nucleus, ua tiav nyob rau hauv cov khoom siv hluav taws xob (ntiv nplhaib).
