I-About Chromium
I-chromium yintsimbi engwevu, ekhanyayo, eqinileyo yentsimbi ethatha upolisho oluphezulu. Iphawuleka ngokumelana kwayo nokutywina. Ineenkqubo zeelektroniki ezingaqhelekanga ezine-4s eyona esebenzayo ngenxa yobume obuzinzileyo be-3d shell epheleleyo.
Iinkqubo
Isinyithi esingaqhelekanga, ukupeyinta kwe-chrome, imibala, ukutywina kwesikhumba, kunye nezinto ezikhuthazayo.
Inyathelo 1:
I-chromium inenkqubo ye-electron engalinganiyo -- 'ithatha' i-electron ukusuka kwi-4s ukunika i-3d orbital epheleleyo.
