Cov thawj valency yog tus naj npawb ntawm cov ions tsis zoo uas sib npaug rau tus nqi ntawm cov hlau ion. Qhov thib ob valency yog tus lej ntawm ligands uas txuas los yog sib koom ua ke rau hlau ion.

Ua li no, dab tsi yog qhov tseem ceeb thiab theem nrab Valencies?

Cov hlau hauv nruab nrab lossis cov hlau atoms hauv kev sib koom ua ke qhia ob hom valency . Lawv yog cov thawj thiab theem nrab valency . Cov thawj valency muaj feem xyuam rau lub xeev oxidation thiab cov theem nrab valency muaj feem xyuam rau tus lej xov tooj. Tus naj npawb ntawm theem nrab valences yog tsau rau txhua lub atom hlau.

Ib yam li ntawd, dab tsi yog qhov Valencies thib ob? theem nrab valence (plural theem nrab valences) (chemistry) nyob rau hauv ib qho kev sib koom ua ke, tus naj npawb ntawm ions los yog molecules uas tau koom tes rau hauv nruab nrab hlau ion; nws tus lej sib koom.

Tsis tas li ntawd, koj yuav nrhiav tau thawj Valency li cas?

Primary Valency (Oxidation State) ntawm Fe = +2

  1. Hauv kev sib koom ua ke, cov hlau qhia ob hom valencies: Primary thiab Secondary.
  2. Cov ntsiab lus tseem ceeb yog ionisable thiab lawv sib npaug rau lub xeev oxidation (them nqi) ntawm cov hlau ion.
  3. Qhov thib ob valencies tsis yog-ionisable thiab lawv sib npaug rau kev sib koom ua ke no.

Koj yuav suav cov Valency theem nrab li cas?

Cov theem nrab valence yog sib npaug ntawm kev sib koom tes thiab yog tsau rau ib qho hlau. Qhov tseeb, cov theem nrab valencies tsis yog ionisable cov khoom muaj nqis . Cov no txaus siab los ntawm nruab nrab molecules los yog tsis zoo ions. Cov theem nrab valency yog tsau rau ib tug hlau thiab yog sib npaug rau cov coordination tooj.
