Sau npe Binary Covalent Compounds

  1. Lub npe cov non-metal furthest mus rau sab laug ntawm lub periodic rooj los ntawm nws cov elemental npe .
  2. Lub npe lwm yam uas tsis yog-hlau los ntawm nws cov elemental npe thiab ib-ide xaus.
  3. Siv cov prefixes mono-, di-, tri-. los qhia tus naj npawb ntawm cov khoom ntawd hauv cov molecule.
  4. Yog tias mono yog thawj lub npe, nws nkag siab thiab tsis sau.

Tsis tas li ntawd, ua li cas koj lub npe binary compounds?

Qhov kev txiav txim rau npe hauv a binary compound yog thawj tus cation, ces anion. Siv cov npe ntawm cation nrog ib tug ruaj oxidation xeev ncaj qha los ntawm lub periodic rooj. Cov npe ntawm cov anion yuav ua los ntawm cov hauv paus hniav ntawm lub caij npe ntxiv rau cov lus "-ide."

Ib yam li ntawd, NaCl puas yog binary compound? Hauv chemistry, a binary compound yog ib yam dab tsi uas muaj ob lub ntsiab. Hauv ib binary compound , tej zaum tsuas muaj ib qho ntawm txhua lub ntsiab lus. Peb pom qhov no nrog sodium chloride (nqaij) NaCl , uas muaj ib qho sodium (Na) thiab ib qho tshuaj chlorine (Cl).

Tsis tas li ntawd kom paub yog, thaum naming binary covalent compound uas lub npe hu ua thawj?

Lub npe binary (ob- keeb ) covalent compounds zoo ib yam li npe yooj yim ionic tshuaj sib xyaw . Cov thawj lub ntsiab nyob rau hauv cov mis tsuas yog teev siv lub npe ntawm tus keeb . Qhov thib ob element npe los ntawm kev noj cov qia ntawm lub keeb lub npe thiab ntxiv lub ntsiab lus -ide.

Hom 3 compounds yog dab tsi?

Hom III binary tshuaj sib xyaw tsis muaj hlau atoms. Muaj ob lub npe sib txawv rau Hom III binary tshuaj sib xyaw : "laus system" thiab "new system." Cov txheej txheem qub siv cov ntawv ua ntej los qhia tus lej ntawm txhua lub atom tam sim no thiab cov txheej txheem tshiab zoo ib yam rau cov uas siv rau npe. Hom II tshuaj sib xyaw.
