Cations yog me me dua lawv niam txiv atoms.
Vim li cas cation me dua niam txiv atom?
Teb tiav:
Qhov no yog vim tus naj npawb ntawm protons tam sim no tshaj li tus lej ntawm electrons Vim li ntawd, muaj tus nqi them, thiab lub atom yog tsis nruab nrab lawm. Raws li qhov tshwm sim ntawm qhov poob electron thaum tsim ib qho cation, cov cation yog me me dua nws niam txiv atom.
Yuav ua li cas me me ntawm niam txiv atom lossis cation?
Cations yog cov atoms lossis cov molecules uas tau poob ib lossis ntau dua electrons muab tus nqi xa tawm ntawm lub atom lossis molecule. … Yog li ntawd, vim qhov poob ntawm electron hauv kev tsim cov cation, qhov loj ntawm cov cation yog me dua nws niam txiv atom.
Puas yog cov cations me dua lawv cov atom?
Feem ntau, cov anions loj dua li cov atom nruab nrab, txij li kev ntxiv cov hluav taws xob ua rau cov hluav taws xob-electron repulsion cuam tshuam uas tshwm sim. Cations me dua li qhov sib thooj nruab nrab atoms, txij li cov valence electrons, uas nyob deb tshaj plaws ntawm lub nucleus, poob.
Yuav ua li cas cation thiab anions piv rau lawv niam txiv atoms?
Anion nce ib qho hluav taws xob, ua kom nws loj dua nws niam atom. Ib qho cation, ntawm qhov tod tes, poob ib qho ntawm nws cov electrons, ua rau nws me dua.
