Hais txog qhov no, lub sij hawm 4 yog dab tsi ntawm lub sij hawm?

Cov ntua 4 Cov hlau hloov pauv yog scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), hlau (Fe), cobalt (Co), nickel (Ni), tooj liab (Cu), thiab zinc. (Zn).

Ib tug kuj tseem nug, vim li cas Lub Sijhawm 4 muaj 18 lub ntsiab lus? Thaum n = 4 , Cov orbital 3d, 4s thiab 3p tam sim no raws li lub plhaub sab nraud qhia tau hais tias qhov ntim hauv kev txiav txim ntawm lawv nce zog nyob rau hauv ib qho kev txiav txim ntawm 3p <4s <4d. Yog li qhov siab tshaj plaws ntawm cov hluav taws xob uas tuaj yeem nyob muaj peb lub orbital 18 yog li no peb thiaj hais tau tias 18 lus yuav tsum muaj nyob rau hauv 4th lub sij hawm.

Tsis tas li ntawd, lub caij twg nyob rau lub sijhawm 4 thiab yog hlau thiab muaj 27 electrons?

A lub sij hawm 4 element yog ib qho ntawm cov tshuaj cov ntsiab lus hauv kab plaub (los yog lub sij hawm ) nyob rau hauv lub periodic table cov ntsiab lus.

Daim ntawv teev npe cov ntsiab lus.

Chemical element 27
Co
Cobalt
Tshuaj series Kev hloov hlau
Electron configuration [Ar] 3d7 4s ib2

Lub caij twg muaj 80 electrons thiab yog ib qho kev hloov pauv?

Mercury
