Yog li cations thiab anions nyiam ib leeg. Hloov chaw, cations repel ib leeg li ua anions. … Qhov tshwm sim yog tias cation-anions attractions tsim ib qho loj uas peb hu ua ionic compound los yog "ntsev". Cov ntawv cog lus tuav cov ions ua ke yog hu ua "ionic" bonds.
Pob cations puas tsim tau ib daim ntawv cog lus ionic?
Nyob rau hauv daim ntawv cog lus ionic, ob cations tuaj yeem sib koom ua ke los ua ib qho kev sib txuas. Thaum ib qho atom tau txais electrons, nws ua tau zoo. … Ib daim ntawv cog lus ionic yog ib qho hluav taws xob hluav taws xob uas tuav ua ke sib txawv ntawm cov atoms hauv ib qho chaw.
Can cations bond?
Cations thiab AnionsIonic daim ntawv cog lus koom nrog cation thiab anion. Daim ntawv cog lus yog tsim thaum lub atom, feem ntau yog hlau, poob ib qho hluav taws xob los yog electrons, thiab dhau los ua ib qho zoo ion, los yog cation. Lwm lub atom, feem ntau yog cov hlau tsis yog hlau, muaj peev xwm tau txais cov hluav taws xob los ua ib qho tsis zoo ion, lossis anion.
Pob cations nyiam lwm cations?
Ib cation yog ib qho zoo them ion nrog tsawg dua electrons dua protons thaum lub anion tsis zoo them nrog ntau electrons tshaj protons. Vim yog lawv cov nqi hluav taws xob sib txawv, cations thiab anions nyiam ib leegthiab nkag mus ua ionic compounds.
Yuav ua li cas yog daim ntawv cog lus tsawg kawg nkaus?
Noble gases yog qhov tsawg tshaj plaws ntawm txhua lub ntsiab lus. Qhov ntawd yog vim lawv muaj yim valence electrons, uas ua rau lawv lub zog sab nraudqib. Qhov no yog qhov ruaj khov tshaj plaws ntawm electrons, yog li noble gases tsis tshua hnov mob nrog lwm cov ntsiab lus thiab daim ntawv sib txuas.
