Chromium muaj rau valence electrons.
Tus naj npawb atomic ntawm chromium yog 24,a hluav taws xob configuration yog 1s22s2 2p63s23p63d54s1 los yog 2,8,13,1 electrons rau lub plhaub. Cov electrons nyob rau hauv 3d54s1 plhaub tsim cov valence electrons raws li tsib electrons nyob rau hauv 3d plhaub koom nyob rau hauv chemical bond tsim.
Hauv qhov no, chromium muaj pes tsawg electrons?
24 electrons
Kuj Paub, koj ua li cas txiav txim siab valence electrons? Rau nruab nrab atoms, tus naj npawb ntawm valence electrons yog sib npaug rau atom lub ntsiab pab pawg naj npawb. Cov pab pawg tseem ceeb ntawm ib lub caij tuaj yeem pom los ntawm nws kem ntawm lub sijhawm teem sijhawm. Piv txwv li, carbon yog nyob rau hauv pawg 4 thiab muaj 4 valence electrons . Oxygen yog nyob rau hauv pawg 6 thiab muaj 6 valence electrons.
Raws li qhov no, MG muaj pes tsawg valence electrons?
2 valence electrons
Dab tsi yog Valency ntawm chromium 3?
Chromium tsim ob qho tib si chloride hauv oxidation xeev +2 thiab + 3 , thiab lawv cov qauv tshuaj yog CrCl2 thiab CrCl3. Li no, lub valencies ntawm chromium tuaj yeem ua 2 thiab 3 , raws li nyob rau hauv cov ntaub ntawv ntawm hlau, uas kuj yog ib tug hloov hlau.
